f3TR1 14-mer cyclic
f3TR1 cyclic peptide phage display library (14-mer)
The f3TR1 14-mer cyclic peptide phage display library is built from the f3TR1 filamentous phage vector ( HM355479.1 ) by replacing a synthetic 14 bp stuffer sequence with frame-restoring 42 bp random oligo nucleotides. The expressed peptides contains cysteines at positions 3 and 12 (XXCXXXXXXXXCXX) constraining the peptide in a cyclic conformation under oxidative conditions. The 14-mer foreign peptide insert is expressed on pIII as a fusion to the N-terminus of pIII through a trypsin-recognition sequence. The f3TR1 phage display library maintains E. coli infectivity and does not require a helper phage for assembly and release of virions.
