Phosphorylation kinetics of various signaling proteins in P116 Jurkat cells. P116 Jurkat cells were treated with or without anti-CD3 for various times and the cellular proteins were separated by PAGE. The tyrosine phosphorylation of specific sites on LAT, PLC-γ1, and SLP-76, along with the expression level of GAPDH, was determined by immunoblotting. For comparison, the phosphorylation of these proteins and the expression level of GAPDH in E6.1 Jurkat cells treated with anti-CD3 for 120 s are shown.
