Fig. 15.
Intracellular phosphotyrosine contents and L-selectin surface expression in thymocytes from control or day 21/2 P-Ir mice. Plots show PTyr and L-sel levels according to the level of CD3 expression as defined in the histograms. Background labelings with irrelevant antibodies (Irrel. Ab) are also shown. Values were obtained with the labeling of pooled thymocytes from at least three animals per point.
