The objective of milestone 28 was to deliver the complete proteome of F. tularensis (FTU) as an arrayed set of proteins of sufficient quantity and quality to productively serve as antigen in T cell immune response screen. The overall goal is to utilize a newly developed proteomic-immunome approach to identify subunit or polypeptide vaccine candidates for Francisella tularensis. In addition to defining the high throughput protocols themselves, ASU also established the data management and quality assurance/control tests needed to ensure the polypeptides’ optimal performance in the T cell based immune screen. These goals have been met. ASU delivered 2,229 FTU synthetically produced and affinity purified polypeptides to the University of New Mexico for use as antigens in high throughput ELISPOT assays. The polypeptides have been evaluated, catalogued, and utlized in T cell experiments. Arraying of the polypeptides into 319 pools of seven polypeptides per pool was performed to streamline the cellular screen; any positive pools will be partitioned to identify individual immunogens to be tested as vaccine candidates. 2 Milestone Objectives The objective of ASU Milestone 28 is to generate a Fransicella tularensis polypeptide library and to ship the arrayed polypeptides in pools to UNM for testing in T cell assays. To support this objective, ASU will build the SCHU S4 proteome, by building the ORF expression library corresponding to the genome and then generating the complete protein-fragment library corresponding to proteome. ASU will implement a high throughput system based on Milestone 26.

Such a method was chosen to overcome the difficulty of cloning a large amount of FTU ORFs using traditional plasmid techniques. T7 promoter was amplified from Novagen pET32b whereas T7 terminator was amplified from pIVEX2.3d. 3.1.2 For cell-free protein synthesis, NEB PURExpress In vitro protein synthesis kits were chosen since they contain minimal amount of cellular E.coli proteins which have shown cross reactivity in ELISpot assay using murine splenocytes. Dynal beads bound thioredoxin antibody were added into the reaction mixture prior to the incubation for protein purification. Bead bound proteins were separated from the reaction mixture, washed, and stored in PBS buffer. 3.2 Critical reagents: 3.2.1 3.2.2 3.2.3 3.2.4 Novagen pET32b for obtaining T7 promoter pIVEX2.3d for T7 terminator NEB PURExpress in vitro protein synthesis kit Magnetic Dynabeads M280 Tosylactivated beads from Invitrogen and monoclonal antithioredoxin antibody from Gene Script Corporation SOP Number1 ASU-Proteome SOP#3 SOP Title High throughput construction and purification of polypeptides 1 Individual Standard Operating Procedures will be reviewed separately and accepted by the Subcontracting PI and UNM PI Page 3 of 26 Tularemia Vaccine Development Contract Contract No. HHSN266200500040-C and ADB Contract No. N01-AI-50040 Prime Contractor: University of New Mexico Milestone Completion Report: MS # 28 Institution: Arizona State University Author: Kathryn Sykes MS Start Date:3/1/2007 MS End Date:12/31/2008 Report Date: 3/4/2009 Version: 2.0 Page 4 of 26 Reviewed by : Barbara Griffith 4/24/09, 7/22/09, 8/10/09, 9/11/09, 10/27/09, 12/23/09, 1/4/10, 1/6/10 4 4.1 Accepted Date:9/11/09 Salient Original Data, Results, Interpretation, Quality Control Original Data and Results (Rationale, Tables/Figures with legends and location annotations) Sub-milestone 28.1: Build ORF expression library corresponding to genome In this section, ASU carried out the first part of the master protocol (Proteome SOP #3 Production and purification of polypeptide libraries). Primers were designed according to the algorithms developed in MS25 and purchased. Using F. tularensis genomic DNA, the 2,229 primer pairs were used to PCR-amplify all intended ORFs. These genes were linked to promoter and terminator sequences in a two-step overlapping PCR protocol as developed in MS26. These linear expression constructs (LEEs) comprised the FTU ORF library. All LEE templates were quantitated by UV-spectrophotometry (Nanodrop 2000) and also fractionated in agarose gels to visualize quantity and quality with ethidium bromide. These data were converted into an e-gel analysis program developed in MS25. The results generated from a portion of these expression templates is displayed on the e-gel in Figure 1.

The validated LEE constructs were used as expression templates in the protocols developed in MS26 for in vitro transcription and translation. Before scaling up to full production, ASU ran a few pilot experiments on the reagents which were purchased in bulk to assure consistency across all polypeptide synthesis. For example, ASU tested a large batch of the reconstituted IVT reaction mix that had been selected in MS26 in order to establish the quality of this specially ordered New England BioLabs (NEB) reagent. A row of 12 templates were expressed with the NEB IVT pure system in the presence of radiolabel. The IVT products were fractionated in SDS-PAGE and visualized by autoradiography. The results in Figure 2 show that the templates and reagents were able Page 5 of 26 Tularemia Vaccine Development Contract Contract No. HHSN266200500040-C and ADB Contract No. N01-AI-50040 Prime Contractor: University of New Mexico Milestone Completion Report: MS # 28 Institution: Arizona State University Author: Kathryn Sykes MS Start Date:3/1/2007 MS End Date:12/31/2008 Report Date: 3/4/2009 Version: 2.0 Page 6 of 26 Reviewed by : Barbara Griffith 4/24/09, 7/22/09, 8/10/09, 9/11/09, 10/27/09, 12/23/09, 1/4/10, 1/6/10 Accepted Date:9/11/09 to generate high quality polypeptide products.

One microgram of LEE template was used for IVT reaction in which 3.3μCi 35S methionine was added for visualization. The total reaction volume is 50uL; 1/10 of this volume was loaded on the gel (Biorad Criterion XT Bis-Tris 4-12%).

This was done by expressing OVA (control) and an FTU (FTU721a) gene template in triplicate reactions. One sample was stored at 4 degrees C for 5 days, one was frozen at -80 degrees C for 5 days and then thawed, and another was not stored at all but was used on the same day. These three unpurified but beadbound samples of two IVT templates were fractionated and visualized. The results in Figure 3 show that no loss of integrity occurs in the samples following the storage and freezing procedures, relative to the product integrity immediately after synthesis. Also, analyses of the bead supernatant following storage showed that there was no reduction in binding of the polypeptides to the beads following 4 degree C storage or a freeze-thaw.

Testing stability of bead-bound IVT polypeptide samples with storage. Ova and FTU LEE were in vitro translated using NEB PURExpress kit and purified using anti-thioredoxin magnetic bead bound antibody. After the reaction was completed, beads were washed and resuspended in 75µL with PBS; 25µL from this volume was used for each storage test. For test 1, the beads were separated from supernatant immediately after the IVT reaction is complete. For test 2, the beads in PBS were stored at 4oC for 5 days. Next, they were separated from supernatant. For test 3, the beads in PBS were stored at -80oC for 5 days. After 5 days, they were thawed on ice and separated from supernatant. Separately, beads and supernatant were mixed with SDS loading buffer containing 5% βmercaptoethanol, heated to 90°c for 5 minutes. Supernatant samples were loaded directly on the gels, whereas only loading buffer mixed with the beads was loaded on Biorad Criterion XT Bis-tris 4-12% gel.

A new large batch of beads and monoclonal (mAb) were prepared and tested in the IVT polypeptide purification protocol defined in MS26. Row A of IVT templates from FTU LEE amplification of FTU Long ORF 2/PCR plate 2 were chosen for the test. The results presented in Figure 4 demonstrate that the Trx mAb bound beads act as a highly efficient ligand for the polypeptides.

The full library products were not radioactively labeled; however, randomly selected sets of templates (12 from each 96-well plate) were run in duplicate to serve as QC samples. The duplicate reactions included 35S-met radiolabel for visualization and quantification of products. An additional positive control template, encoding green-fluorescence protein (GFP), was included as a non-FTU gene sample The mass yield of each QC sample was determined by two methods. First, the amount of incorporated radioactive 35S-methionine (met) label precipitated with trichloroacetic acid (TCA) was calculated based on specific activities and the known number of methionine in each polypeptide based on the manufacture calculation formula as shown in ASU Proteome SOP#3 Second, samples were fractionated in SDSPAGE and gray-scale intensity was measured by densitometry. For this experiment the antibody-captured IVT products (calmodulin) were eluted from the bead-antibody conjugate prior to fractionation. Sample band intensities were compared to a titration of protein standards (GFP). The recombinantly produced GFP had been quantitated by BCA (bicinchoninic acid) protein assay, and run on the same SDS page gel. The Coomassie stained gel of purified recombinant GFP used as protein standards and IVT-generated, TCA-quantitated calmodulin is shown in figure 7. Based on TCA assay, the total yield of lane 2 is 0.97ug compared to 0.90ug from densitometry method. The difference between calculation of IVT protein yield from the TCA assay and densitometry method is approximate 7%.

An Invitrogen control vector carrying the Calmodulin gene was used as the test template. As protein standards, recombinantly produced GFP protein purified by nickel affinity column chromatography (0.1 to 1.0ug/lane) was used. NOTE 1: The GFP protein was recombinantly produced and nickel bead purified to obtain mass quantities of protein as a concentration standard. Thus the GFP protein preparation does not contain other protein bands. NOTE 2: ASU had already repeatedly demonstrated that the linear and circular plasmid templates perform similarly. It was easier and less expensive to use plasmid templates for the developmental phases and then after development, ASU performed a final confirmation of the optimized protocol with a PCR product as template. A PCR-produced or gene-built produced piece of DNA will not differ in structure NOTE 3: For two reasons, the purified calmodulin polypeptide in lane 2 of figure 7 does not show the immunoglobulin chains that were visible in the lanes of Figure 6 above. Reason 1: The calmodulin polypeptide in figure 7 was eluted from the bead-antibody conjugate, whereas the FTU polypeptides in Figure 6 were retained onto beads. So, when the FTU samples (bead, Ab, polypeptide) were run on a gel in figure 6, the heavy and light immunoglobulin chains were present and stainable. Reason 2: The calmodulin protein is well known to be very efficiently translated in these in vitro reactions. There is always more calmodulin polypeptide made than other samples by these IVT lysates. So, this results in the low levels of lysate components visible in F-6 but not visible in the small proportion of calmodulin sample fractionated in F-7 as shown in lane 2. NOTE 4: In F-7, lane 2, the FTU polypeptide was eluted from the beads as follows. An equal volume of .2M NaOH is added to the beads/polypeptide/antibody complex to make a final concentration of .1M NaOH. The base disassociates the Trx-polypeptide from the anti-trx antibody, but the antibody remains attached to the beads. The beads/antibody complex is separated by the magnets and the supernatant containing the polypeptide is assayed on the gel in Figure 7.

After the IVT reactions were completed, supernatants were removed, and products bound to beads were washed and stored in a final volume of 100ul PBS/ reaction. This bead volume then was split into two 50ul aliquots. One was used for pooling, and the remaining half-reaction aliquot was stored at 80 oC to be used in a future experiment. To prepare the first half of each reaction for cellular assays at UNM, polypeptides were pooled by columns 1 through 12 of each 96 well plate. Since the last row (H) of each plate was left empty, each library plate contained only 7 rows (A to G) of FTU polypeptides.

Initially the total volume of each pool was 350ul (50ul x 7 IVT products). ASU added 50ul of PBS into each pool to make a total pool volume of 400ul, representing 360ul plus a 10% volume margin in order to accommodate pipetting loss during distribution. From each 360ul of pooled product, ASU split off 180ul for UNM’s first polypeptide test with 2 plates (90ul of pooled product/plate) of splenocytes and the other 180ul for testing with 2 plates (90ul of pooled product/plate) of lymph node cells from LVS vaccinated NHPs. NOTE: All samples were normalized to the amount of beads. The ranges and average amounts of the full library should be that of the pools. F-9. Distribution of each polypeptide pool into four aliquots for use in immune cell assays. These F.tularensis antigen pools circled in Figure 9 were sent to UNM on January 5, 2009. The remaining half set of IVT reactions was stored at ASU for the second NHP experiment at UNM. 4.2 Interpretation The planned objective for this milestone was to implement the high throughput IVT protocol developed in milestone 26 for the 2,229 polypeptides representing the full FTU proteome. While ASU carried out numerous tests during protocol development to provide the highest probability of success, scaling up is rarely straightforward. ASU conducted multiple pilot and quality control tests of all reagents and procedures used to ensure successful synthesis of the 2,229 polypeptides to complete Milestone 28.
