Detection of Human/Mouse/Rat ERK1/ERK2 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, PC-12 rat adrenal pheochromocytoma cell line, and TS1 mouse helper T cell line. PVDF membrane was probed with 0.5 µg/mL Mouse Anti-Human/Mouse/Rat ERK1/ERK2 Monoclonal Antibody (Catalog # MAB1576) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, recombinant human ERK1 and ERK2 (2 ng/lane) were included. A specific band for ERK1/ERK2 was detected at approximately 44/42 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 4.
ERK1/ERK2 in Human Brain. ERK1/ERK2 was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using Mouse Anti-Human/Mouse/Rat ERK1/ERK2 Monoclonal Antibody (Catalog # MAB1576) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cell bodies. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

ERK1 and ERK2 (also known as MAPK3 and MAPK1) are 44 and 42 kDa Ser/Thr kinases, respectively. They are part of the Ras-Raf ERK signal transduction cascade often found downstream of growth factor receptor activation. ERK1 and ERK2 were initially isolated and cloned as kinases activated in response to insulin and NGF. They are expressed in most, if not all, mammalian tissues. Dual threonine and tyrosine phosphorylation activates both ERKs, at Thr202/Tyr204 for human ERK1 and Thr185/Tyr187 for human ERK2. The two proteins share 83% amino acid identity, differing mainly at the N and C termini.
