MIM™-12 Phage Display Peptide Library Kit
Technical Description
The MIM™-12 Phage Display Peptide Library consists of ~109 random linear 12-mer peptides displayed as an N-terminal fusion protein with the minor coat protein pIII on the head of the fd filamentous bacteriophage. The sequence of the insert is NH2-X12GGGSGPGGLRGGS-pIII after cleavage of the leader peptide. The library was built on the phage vector fADL-2blue using degenerated NNK codons. fADL™-2blue is a multivalent type 3 phage display vector (Smith 1997) derived from the phage vector fd-tet (Zacher 1980). fADL-2blue is well tolerated by the host and gives large colonies and small plaques, simplifying the screening of libraries and the handling of single clones. Helper phage are not required for amplification. The linker GGGSGPGGLRGGS is sensitive to trypsin, enabling trysin elution, which has been show to improve motif recovery (Thomas 2010).

The MIM™-12 Phage Display Peptide Library Kit holds enough material for 10 panning experiments (Fig. 1). Each aliquot of 10 µl contains 2 x 1010 cfu, equivalent 20 transducing units per peptide on average. Panning of the library leads to the rapid identification of peptide binders (Fig. 2).
Figure 2. M2 Antibody Epitope Mapping. Panning of the MIM-12 library by the FLAG® tag M2 antibody leads to all sequences analyzed with motifs matching the tag sequence on the third round.
Applications
Epitope mapping.
De novo isolation of peptide binders.
