Anti-MAP2K1 Antibody E237
Also for MAP2K1 (NM_002755)
|A synthetic phospho-peptide corresponding to residues surrounding Ser218 and Ser222 of human MEK1 was used as immunogen. The antibody only detects MEK1 phosphorylated on Serine 218 and 222.|

|MEK1 and MEK2 (MAPK kinase 1/2, or ERK kinase 1/2) are mitogen-activated protein kinases that stimulate MAP kinase activity, playing a role in both cell growth and differentiation (1,2). MEK itself is activated via phosphorylation at serines 217/218 and 221/222 by upstream activator kinases, including c-raf, mos and MEK kinase (3,4). MEK1 and MEK2 are activated by a wide variety of growth factors and cytokines, and also by membrane depolarization and calcium influx (5).|

Western blot - MEK1 (phospho S218 + S222) antibody [E237]; All lanes : Anti-MEK1 (phospho S218 + S222) antibody [E237] at 1/1000 dilution.Lane 1 : Serum starved A431 cells lysate.Lane 2 : EGF treated serum starved A431 cells. lysate.Predicted band size : 45 kDa.Observed band size : 43 kDa .
Immunohistochemistry (Paraffin-embedded sections) - MEK1 (phospho S218 + S222) antibody [E237]; Ab32088, at a 1/50 dilution, staining MEK1 in paraffin embedded skin carcinoma tissue sections by Immunohistochemistry.
Immunocytochemistry/ Immunofluorescence - Anti-MEK1 (phospho S218 + S222) antibody [E237]; ab32088 staining MEK1 (phospho S218 + S222) in SKNSH cells treated with dopamine hydrochloride , by ICC/IF. Increase in MEK1 (phospho S218 + S222) expression correlates with increased concentration of dopamine hydrochloride, as described in literature.The cells were incubated at 37°C for 24h in media containing different concentrations of (dopamine hydrochloride) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab32088 (1/100 dilution) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
