Update History


All but 10 of the documents in this webpage (see the table of descriptions below) were updated or posted anew in the period 2/28/06 to 3/4/06; a list of the most recent document modification dates can be found in ModificationDates.doc. As newly modified documents are posted subsequent to that time, they will be listed below, the most recent postings at the top.

Posted 3/22/06 5:00 PM Central Standard Time: Minor corrections to stdpreps.doc, vectors.doc; see below under Distribution Policy for newly posted Kit5.doc.

Posted 3/9/06 Noon Central Standard Time: Changes to AffinitySelection.doc, vectors.doc, stdpreps.doc and KitRequest.doc describing use of (and allowing requests for) fd-cat internal enrichment control phage

Posted 3/5/06 2:00 AM Central Standard Time: RPLconstruct.DOC updated (minor change: graph inserted at last step)


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 materials will have labels that reference a distribution document called Kit#.doc, where # is a serial number; that document will contain our internal references for the distributed materials, and may be useful information to us in answering questions. Here are links to the distribution documents and their posting dates.

Posted 3/22/06: Kit5.DOC


A basic review of phage display from Chemical Reviews 1997: PetrenkoSmithChemReviews.PDF


Standard Preparations and Procedures are referred to in italics


Throughout the documents on this webpage, 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 Webpage Contains Links to Documents That Describe Our Phage-Display System and How to Use It


This document contains numerous links to Microsoft Word documents (as well as to the pdf document above), each of which details some specific aspect of the phage-display system.  In order to be accessible, a document must previously have been downloaded from this website, using the links on this page.  These documents cross-reference each other extensively through local hyperlinks (using relative paths), which will work only if all the documents are downloaded to 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, you should certainly download MainIndex.doc (basically a Microsoft Word version of the present webpage, containing brief descriptions of and hyperlinks to all the other Word documents) and the above-mentioned stdpreps.doc (containing standard preparations and procedures referenced in almost all the other documents).
