ERK2 Antibody, pAb, Rabbit

USA

GenScript Rabbit Anti-ERK2 Polyclonal Antibody detects endogenous levels of human, mouse and rat ERK2 (p42 MAP Kinase) and slightly cross-reacts with ERK1 (p44 MAP Kinase).

ERK (extracellular signal regulated kinase), also known as MAPK (mitogen activated protein kinase) includes two closely related isoforms ERK1 and ERK2 (p44 and p42 MAP Kinase). ERK1/2 signaling pathway can be activated in response to a diverse range of extracellular stimuli including mitogens, growth factors, and cytokines. The downstream effects of ERK1/2 signaling pathway are linked to the regulation of cell growth and differentiation as well as the cytoskeleton. Downstream targets of ERK1/2 contain p90RSK and the transcription factor Elk-1. ERK1 and ERK2 are phosphorylated within the activation loop on both a threonine and a tyrosine residue (within a Thr-Glu-Tyr motif) by MEKs (MAPK/ERK kinases), thereby greatly elevating the activity of ERK1/2. ERK1/2 are negatively regulated by a family of dual-specificity (Thr/Tyr) MAPK phosphatases. GenScript, Rabbit Anti-ERK2 Polyclonal Antibody, is developed in rabbit using a KLH-coupled synthetic peptide (KRIEVEQALAHPYLEQYYDPSDE) corresponding to 300-322 residues of human ERK2 (Swiss Prot: P28482).

Immunoaffinity chromatography

Small volumes of antibody will occasionally become entrapped in the seal of the product vial during shipment and storage. Before use, briefly centrifuge the vial to dislodge any liquid in the container's cap.
