Species cross-reactivity is determined by western blot using the unconjugated antibody.
Applications Key: W=Western Blotting
Specificity / Sensitivity
MEK1 (61B12) Mouse mAb (Biotinylated) recognizes endogenous levels of total MEK1 protein. This antibody does not cross-react with MEK2 and other MAP kinase kinases.
Source / Purification
Monoclonal antibody is produced by immunizing animals with full length MEK1 proteins.
This Cell Signaling Technology antibody is conjugated to biotin under optimal conditions. The biotinylated antibody is expected to exhibit the same species cross-reactivity as the unconjugated MEK1 (61B12) Mouse mAb #2352.
MEK1 and MEK2, also called MAPK or Erk kinases, are dual-specificity protein kinases that function in a mitogen activated protein kinase cascade controlling cell growth and differentiation (1-3). Activation of MEK1 and MEK2 occurs through phosphorylation of two serine residues at positions 217 and 221, located in the activation loop of subdomain VIII, by Raf-like molecules. MEK1/2 is activated by a wide variety of growth factors and cytokines and also by membrane depolarization and calcium influx (1-4). Constitutively active forms of MEK1/2 are sufficient for the transformation of NIH/3T3 cells or the differentiation of PC-12 cells (4). MEK activates p44 and p42 MAP kinase by phosphorylating both threonine and tyrosine residues at sites located within the activation loop of kinase subdomain VIII.
