H-thymidine incorporation responses of P-b2–derived clones to b2a2 17mer peptides with single aa substitutions to alanine. Single letter coded aa represent b2a2 peptides in which the given aa is substituted to alanine. Response (minus the background) <20% of that of the clone to unaltered 17mer peptide: −, 20% to 60%: +, 60% to 120%: ++, >120%: +++. Peptide concentrations, 5 μg/mL.
