MEK1 / 2 (phospho Ser218 / Ser222) Antibody | XPS-1018

MEK1 / 2 (phospho Ser218 / Ser222) Antibody | XPS-1018 | Gentaur UK, US & Europe Distribution

Host: Rabbit

Reactivity: Human, Mouse, Rat, Frog

Homology: N/A

Immunogen: MEK 1/2 (Ser218/222) polyclonal antibody was raised against a synthetic phosphopeptide corresponding to amino acids residues surrounding the phosphoSer218/222 of human MEK 1/2.

Research Area: Signal Transduction, Phospho-Specific

Tested Application: WB

Application: The antibody immunolabels the ~45k MEK protein in a Western blot of serum-stimulated NIH 3T3 cells. The immunolabeling is blocked by the phosphopeptide used as antigen but not the corresponding non-phosphopeptide. Applications include Dot Blots (DB) and Western Blots (WB) . Suitability for Immunohistochemistry (IHC) has not yet been determined. Human, mouse, rat and Xenopus have 100% amino acid sequence identity with the antigen used to raise the antibody. When internally tested under ideal conditions the working dilutions were 1:1000 for DB and WB.

Specificiy: MEK1/2 antibody is specific for MEK 1/2 phosphorylated at Ser218/222.

User Note: Optimal dilutions for each application to be determined by the researcher.

BACKGROUND: MEK 1 and MEK 2 are integral components of the MAP kinase cascade that regulates cell growth and differentiation and this pathway also plays a key role in synaptic plasticity in brain. Activation of MEK 1/2 occurs 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. This phosphorylation of ERK by MEK 1/2 is a critical step in the MAP kinase cascade.
