Peptide with more than 18 amino acids will be charged pro rata. We can provide assistance on designing peptide with respect to protein homology, antigenicity, hydrophilicity, and synthetic suitability. 1.5 week HPLC purification if peptide purity is <90%. 2 Conjugation Conjugation of 4 mg peptide (using Cystein) to KLH. 0.5 week Conjugation to IKERSA (an unique 28 kDa recombinant protein from Immunokontact, conjugation using Cysteine residue at the N-terminal of peptide) for western blotting analysis and other functional studies. TM 3 Immunization and anti-sera production Conjugated peptides or recombinant proteins are used to immunize rabbits. See next page for detail protocol. 7-10 weeks Ten-week protocol to produce antibodies in 2 rabbits. Pre-immune and three immune bleeds (100-120 ml antiserum). 4 Test ELISA test until the titre reaches 1:4,000. 1 day Western blot analysis when ELISA reaches target titre. 5 Purification Protein G purification 1 week Antibodies are eluted using both pH11 and pH2.5 buffers and neutralized immediately followed by dialysis in PBS See Rabbit Polyclonal Antibody Production Protocol for detailed description of steps 3-5. 6 10-13 weeks Total Additional Options SERVICE 3 4 5 DESCRIPTION TIME Immunization and anti-sera production Add for each additional rabbit Test Immunohistochemistry on tissues or cultured cells 1 week Immunoprecipitation on tissue or cell lysate 1 week Peptide affinity purification 1 week Purification Extend protocol for each additional week UNITED KINGDOM, INTERNATIONAL: AMS BIOTECHNOLOGY (EUROPE) LTD.

The antigen and adjuvant are mixed thoroughly to form a stable emulsion that is injected beneath the skin of the rabbit (subcutaneously) in the area around the shoulders and intra-muscularly into the large muscle of the rear legs. (That is about 1/4 of the antigen being used in each area). This provides enhanced immune response from the sustained presentation of the immunogen. 5 Bleeds Blood is collected from the central ear artery with a 19-gauge needle and allowed to clot and retract at 37°C overnight. The clotted blood is then refrigerated for 24 hours before the serum is decanted and clarified by centrifugation at 2,500 RPM for 20 minutes. 6 Schedule Week 0 7 Note Bleed 10 ml (yields 5-8 ml pre–immune serum) Immunize with 200 g/rabbit antigen in CFA. Week 1 Immunize with 100 g/rabbit antigen in IFA. Week 2 Immunize with 100 g/rabbit antigen in IFA. Week 3 Immunize with 100 g/rabbit antigen in IFA. Week 4 Immunize with 100 g/rabbit antigen in IFA. Week 5 Test bleed 20-30 ml. ELISA on appropriate cell/tissue. Immunize with 100 g/rabbit antigen in IFA. Week 6 1St Production bleed 20-30 ml if test positive. Immunize with 100 g/rabbit antigen in IFA. ELISA test again if previous tests were negative. Week 7 2nd Production bleed 20-30 ml. Immunize with 100 g/rabbit antigen in IFA. ELISA test again if previous tests were negative. The continuation of the project needs to be discussed if negative. Week 8 3rd Production bleed 20-30 ml. Immunize with 100 g/rabbit antigen in IFA. Week 9 4th Production bleed 20-30 ml. Immunize with 100 g/rabbit antigen in IFA. Week 10 Terminating bleed 100-120 ml. Protein G purification of pooled bleeds. Average yield of purified Ig fraction is 100-150 mg. Final ELISA and WB QC test. The rabbits can be maintained on a ten-weeks cycle of immunizations and bleeds as required by the project. The results of testing will determine whether the program should be continued, modified, or terminated. Extra bleeds can be taken upon customer’s requirement of extended project with extra charge.
