The epitopes, recognized by four MAbs, had already been identified at low levels of resolution. Complementary oligonucleotides encoding ten amino acid fragments, with five amino acid overlaps were designed with suitable sticky ends for recombination with pET-32a and subsequent expression as small-fragment fusion proteins. Antigenicity of specific oligopeptides was determined by Western blotting with the MAbs. Using the same methods, amino acids were deleted one by one from the peptides of interest, enabling the two epitopes to be precisely located at amino acids 430-435 (-DRIMNP-) and 643-647 (-VFIKN-).展开更多
