Confocal immunofluorescent analysis of HeLa cells, treated with PDBu (100 nM, 15 min; left) or U0126 #9903 (10 μM, 2 hr; right), using Phospho-p44/42 MAPK (Erk1) (Tyr204)/(Erk2) (Tyr187) (D1H6G) Mouse mAb (green) and β-Actin (13E5) Rabbit mAb #4970 (red).
Flow cytometric analysis of Jurkat cells, treated with U0126 #9903 (10 μM, 2 hr) (blue) or TPA #4174 (200 nM, 15 min) (green), using Phospho-p44/42 MAPK (Erk1) (Tyr204)/(Erk2) (Tyr187) (D1H6G) Mouse mAb. Anti-mouse IgG (H+L), F(ab') 2 Fragment (Alexa Fluor ® 488 Conjugate) #4408 was used as a secondary antibody.
