Phage display assay

A method of producing specific binding members for a cell surface antigen, wherein cells with the antigen at their surface and control cells without the antigen at their surface are immobilised on a solid surface, without fixation, and are contacted with a phage display library with blocking of non-...

Zusammenfassung:A method of producing specific binding members for a cell surface antigen, wherein cells with the antigen at their surface and control cells without the antigen at their surface are immobilised on a solid surface, without fixation, and are contacted with a phage display library with blocking of non-specific binding, and a population of phage displaying specific binding members for the cell surface antigen is identified, the method further comprising obtaining nucleic acid which has a nucleotide sequence encoding specific binding members displayed on phage of the population and producing one or more specific binding members for the cell surface antigen by recombinant expression from nucleic acid with the nucleotide sequence or a derivative nucleotide sequence to produce a product specific binding member.
