FIG. 2.
Proliferation (plus standard deviation) of gp43-sensitized BALB/c LN cells induced by 25 peptides spanning the whole sequence of the native gp43 molecule. P10, the only responding peptide, has 15 amino acids. The peptides were tested at 10 μg/ml. C, control with no antigen added; PH, phytohemagglutinin at 5 μg/ml; CA, concanavalin A at 2 μg/ml (positive controls); gp43 was at 50 μg/ml.
