Smith Division of Biological Sciences Tucker Hall University of Missouri Columbia, MO 65211-7400 (573) 882-3344 (office) (573) 882-2720 (lab) smithgp@ missouri.edu (e-mail) Distribution Policy Unless we specifically stipulate otherwise, you are free to pass on any materials obtained from our lab to any other user. Until further notice, we plan to continue our long-standing policy of distributing our “kit” (vector and E. coli host strains) and amplified random peptide libraries free to anyone who asks, including to commercial enterprises. To request materials, download KitRequest.doc and follow instructions. We no longer accept requests for standard phage-display materials in other forms, including in the body of e-mails or in letters; such requests will simply be discarded without notification. However, we do try to respond to other communications, including requests for special materials not covered in the the KitRequest document. Standard Preparations and Procedures are referred to in italics Throughout this manual components that are made from stock solutions given in stdpreps.doc are printed in italics. Also printed in italics are a number of standard methods that are also explained in that document. This Document Contains Descriptions of and Hyperlinks to Other Documents That Describe Our Phage-Display System and How to Use It This document contains numerous hyperlinks to other Microsoft Word documents, each of which details some specific aspect of the phage-display system. In order to be accessible though a hyperlink, a document must previously have been downloaded from our website at http://www.biosci.missouri.edu/smithgp/PhageDisplayWebsite/PhageDisplayWebsiteIndex.html. Clicking on a hyperlink opens the document. The hyperlinks use relative (local) paths, and will therefore only work if all the documents (including this one) are in the same directory (folder). The documents are largely self-contained, however, so it isn’t necessary to download all of them. Whatever else you download (besides the present document), you should certainly download the above-mentioned stdpreps.doc, which contains standard preparations and procedures referenced in almost all the other documents. 106728485 02/12/16 Page 2 List of documents Contents Basic review of phage display from Chemical Reviews 1997 Standard preparations (solutions, media, etc.) and procedures referenced in almost all the other documents Description and confirmation of E. coli strains Description of fUSE vectors (display on gene III protein) and f88 vectors (display on gene VIII protein) Random peptide libraries in Descriptions of libraries fUSE5 and f88-4 vectors Sequences of insert regions Form for requesting vectors, libraries or strains Amplifying a large phage-display library without losing diversity Biotinylation of a receptor for use in affinity selection and binding assays Affinity selection (“biopanning”): using a target selector (receptor, antibody, other binding molecule) to select binding clones from large libraries 1-ml scale propagation and processing of clones for sequencing and binding assays (we never do this any more) 7-ml scale propagation and partial purification of virions Extraction of ssDNA from virions for sequencing or other purposes Manual procedure for sequencing inserts in large numbers of clones (we never do this any more) Binding assays Phage capture assay (miniaturized for confirming analytical version of affinity selection, affinty of phage in which the input is individual clones clones for target rather than complex populations) receptor Quantifying binding of selector to phage clones immobilized on the surface of plastic wells (Continued next page) Document PetrenkoSmithChemReviews.PD F stdpreps.doc Strains.doc vectors.doc library.doc libeseq.doc KitRequest.doc AmplifyingLibrary.doc biotinylation.doc AffinitySelection.doc Propagation_1ml.doc SmallScaleVirions.doc ssDNA.doc sequencing.doc micropan.doc ELISA.doc 106728485 02/12/16 Page 3 List of documents (continued) Contents Preparation of large quantities of double-stranded circular vector RF DNA for cloning.
