f88-4 cys5 cyclic peptide phage display library (15-mer)
The f88-4 cys5 cyclic 15-mer peptide phage display library is built from the
f88-4 filamentous phage vector (AF218363.1) by replacing a synthetic 21 bp stuffer sequence with frame-restoring 45 bp random oligo nucleotides. The resulting phage particles express the wild-type gene VIII and an artificial gene rVIII. The 15-mer foreign peptide insert is expressed on rVIII. The expressed peptides contains cysteines at positions 5 and 11 (XXXXCXXXXXCXXXX) constraining the peptide in a cyclic conformation under oxidative conditions. The f88-4 phage display libraries maintain
E. coli infectivity and do not require a helper phage for assembly and release of virions.
