Datasheet Extract

Synthetic peptide (coupled with KLH) derived from aminoacid sequence 33-53 of human MAPK Kinase 1.
The immunogen sequence is highly conserved within species (human, mouse, rat, hamster, bovine etc.).
Property pSer218/222
Application Western Blotting under reducing and non-reducing conditions:
Recommended dilution: 0.5 μg/ml
Positive material: RAJI human Burkitt lymphoma cell line
Sample preparation: Resuspend approx. 50 mil. cells in 1 ml cold Lysis buffer (1% laurylmaltoside in 20 mM Tris/Cl, 100 mM NaCl pH 8.2, 50 mM NaF including Protease inhibitor Cocktail). Incubate 60 min on ice. Centrifuge to remove cell debris. Mix lysate with non-reducing/reducing Laemmli SDS-PAGE sample buffer. Boil for 5 min.
Reducing conditions are recommended.
Background MEK (MAPKK, kinase of mitogen-activated protein kinase) is the medium one of three components of MAP kinase cascade - an important signaling pathway that regulates cell growth and differentiation. Raf (MAPKKK) activates MEK 1 and 2 via phosphorylation of two serine residues (Ser218 and Ser222). Activated MEK 1/2 then acts as a dual specificity kinase phosphorylating both a threonine and a tyrosine residue on ERK (MAPK, mitogen-activated protein kinase). This phosphorylation of ERK by MEK 1/2 is a critical step in the MAP kinase cascade. Phosphorylated ERK is capable of translocating to the nucleus, where it regulates gene expression by activating transcription factors.
Concentration 1.0 mg/ml

Storage Store the antibody undiluted at 2-8°C for one month or (in aliquots) at -20°C for longer.
Avoid repeated freezing and thawing.
Shelf life: one year from despatch
Immunoffinity chromatography.
Buffer System:
PBS containing 15 mM sodium azide as preservative and 0.2% (w/v) high-grade BSA (Protease free) as stabilizer.
Liquid purified IgG fraction (> 95% pure by SDS-PAGE).
The polyclonal antibody reacts with MEK 1/2. MEK 1 and MEK 2 are integral components of the MAP kinase cascade, an important pathway for cell growth and differentiation.
