Antibody-secreting hybridoma cell lines produced from BALB/c mice that had been immunized with horse cytochrome c (cyt c) conjugated to hemocyanin yielded six hybridoma subclones that produced four monoclonal antibodies (mAb) with different patterns of cross-reactivity with a panel of evolutionarily variant cyt c. The recognition sites for three of these mAb lay in the same region of the intact molecule, because two of the mAb were sensitive to the amino acid residue present at sequence position 44, with one requiring threonine at position 47. The fourth mAb bound in another region of the molecule at a site that involves either residue 60 or residue 89. Synthetic peptides that included these..View full abstract
