Detection of Human Phospho-MEK1 (S218/S222)/ MEK2 (S222/S226) by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line and HeLa human cervical epithelial carcinoma cell line untreated (-) or treated (+) with 200 nM PMA or PMA and Ionomycin for 20 minutes. PVDF membrane was probed with 0.5 µg/mL of Rabbit Anti-Human/Mouse/Rat Phospho-MEK1 (S218/S222)/ MEK2 (S222/S226) Monoclonal Antibody (Catalog # MAB8407) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-MEK1 (S218/S222)/ MEK2 (S222/S226) at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: MEK1/MEK2

MEK1 and MEK2, also known as MAP2K1 and MAP2K2, are activated in response to mitogenic stimuli. Activation occurs through dual phosphorylation at S218/S222 of MEK1 and S222/S226 of MEK2 by several upstream MAP3Ks, including the Raf kinases. Both MEK1 and MEK2 are dual-specificity protein kinases, phosphorylating and activating ERK1 and ERK2 at Thr and Tyr positions.
