abstract

  • Sets of overlapping synthetic peptides for three well characterized proteins (sperm whale myoglobin, hen egg lysozyme, and the circumsporozoite protein from Plasmodium falciparum) were prepared and examined by reversed-phase high-performance liquid chromatography (RP-HPLC). Using retention coefficients to predict the retention time of each peptide, several peptides in each protein set were found that exhibited anomalous behavior (i.e. eluted significantly later than predicted). Previous work with model peptides has shown that this anomalous behavior can be attributed to specific amphipathic arrangements induced by the lipid stationary phase during the RP-HPLC process. In the current study it was found that although not all of the peptides containing an antigenic T cell site displayed anomalously late behavior, all of the peptides which eluted anomalously late during RP-HPLC included the regions of these proteins known from earlier studies to be antigenic T cell sites. © 1992.
