Figure 1.

Proliferative responses of spleen cells from BALB/c mice primed with p127–142 of Bos d 2 upon stimulation with its alanine-substituted analogues. The results are presented as mean counts per minute (c.p.m.) (± standard error of the mean) for four independent experiments. The peptide concentrations were 15 µm (solid bars) and 1·5 µm (open bars). The medium background has been subtracted (< 1400 c.p.m. in all tests).
