特異性：Detects endogenous levels of MEK1/2 only when activated by phosphorylation at Ser217/221. Does not crossreact with related kinases including activated SEK (MKK4), MKK3 or MKK6. It will also react with MEK1/2 singly phosphorylated at Ser217, but not with MEK1/2 singly phosphorylated at Ser221. Species Crossreactivity: Human, mouse and rat.
純度：Affinity Purified Purified by Protein A affinity chromatography.
形状：Supplied as liquid in 10mM HEPES, pH 7.5, 150mM sodium chloride, 0.1mg/ml BSA, 50% glycerol. No preservative added.
