Our Anti-MEK1 (Thr292) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human and mouse MEK1 (Thr292) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of recombinant wild type MEK 1 (WT) and mutant MEK 1 (T292A) (Mut). Specific immunolabeling of the ~45 kDa MEK-1 protein phosphorylated at Thr292 is shown in the second lane where MAP kinase was coexpressed.
Anti-MEK1 (Thr292) Antibody
MEK 1 (MAP kinase kinase, also known as MKK) is an integral component of the MAP kinase cascade that regulates cell growth and differentiation (Ahn, 1993; Chong et al., 2003). This pathway also plays a key role in synaptic plasticity in the brain (Adams and Sweatt, 2002). Activated MEK 1 acts as a dual specificity kinase phosphorylating both a threonine and a tyrosine residue on MAP kinase (Kyriakis et al., 1991; Seger et al., 1991; Crews et al., 1992). Conversely, there also appears to be a feedback phosphorylation of MEK 1 by MAP kinase. The sites on MEK 1 that are phosphorylated by MAP kinase are Thr-292 and Thr-386 (Mansour et al., 1994).
Antigen Affinity Purified from Pooled Serum
Synthetic phospho-peptide corresponding to amino acid residues surrounding Thr292 of human MEK1, conjugated to keyhole limpet hemocyanin (KLH).
Bovine, Canine, Non-Human Primate, Rat
Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
Prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho and non-phosphopeptide affinity columns.
