Abstract:
:A consensus peptide sequence, QSYP, appears as an artifact during the mapping of monoclonal antibodies (MAbs) using a random peptide phage display library. Phage bearing this QSYP sequence were independently selected by four different laboratories screening separate MAb preparations with the same phage library. In each case, the QSYP sequence was selected in addition to a consensus sequence specific to the MAb. Phage that displayed the QSYP sequence were not bound by the MAb of interest, but rather bound to bovine IgG derived from the FBS present in the hybridoma growth media. The implications of this finding for the interpretation of phage library screening results and possible methods for the removal of bovine IgG from MAb preparations are discussed.
