Product Info
Background The mitogen-activated protein kinases (MAPK) consist of several subgroups, including the ERK, JNK, and p38 kinases. The members of this MAPK family are regulated by many different extracellular cues ranging from cytokines, growth factors, and neuropeptides (1). These stimuli activate cell surface receptors to stresses such as cold, heat, osmolarity changes and irradiation. The pathways regulated by the MAPKs control a broad array of cellular responses ranging from survival, cell proliferation, and apoptosis (1,2). The MAPKs family is also characterized by their requirement for dual phosphorylation at a conserved threonine and tyrosine residue for enzymatic activation and both must be phosphorylated for full enzymatic activation (3). The closely related ERK1 (44 kDa) and ERK2 (42 kDa) kinases are characterized by their requirement for dual phosphorylation at a conserved T-E-Y motif (4,5). While JNK1 is activated by dual phosphorylation at a T-P-Y motif and p38 is also activated by dual phosphorylation at a T-G-Y motif (6,7). 
Origin ERK2 (C14) is provided as an affinity purified rabbit polyclonal antibody, raised against a peptide mapping to the carboxy terminus of rat ERK2. 
Product Details Each vial contains 200 g/ml of affinity purified rabbit IgG, ERK2 (C14) DB020, in 1 ml PBS containing 0.1 % sodium azide and 0.2% gelatin. 
Competition Studies A blocking peptide is also available, DB020P, for use in competition studies. Each vial contains 0.100 mg of peptide in 0.5 ml PBS with 0.1% sodium azide and 100 mg BSA. 
Form 200 g/ml rabbit polyclonal IgG in 1 ml PBS containing 0.1 % sodium azide and 0.2% gelatin. 
Immunogen Synthetic peptide mapping to the carboxy terminus of rat ERK2. 
Western blot analysis of ERK2 expression in A431 (A), HeLa (B), HL-60 (C) and NIH/3T3 (D) whole cell lysates. 
Use ERK2 (C14) DB020 reacts with ERK2 p42 and to a lesser extent ERK1 p44 of mouse, rat and human origin by western blotting, immunoprecipitation, and immunohistochemistry. Western blotting starting dilution: 1:400.
