Rabbit polyclonal antibody to MEK1 / MEK2 (Phospho-Ser217 / Ser221)
Specificity
The antibody detects endogenous level of MEK1 / MEK2 only when phosphorylated at serine 217 / 221.
Applications
IHC, WB
Reactivity
Human, Mouse, Rat
Immunogen
Peptide sequence around phosphorylation site of serine 217 / 221 (I-D-S(p)-M-A) derived from Human MEK1 / MEK2.
Host
Rabbit
Clonality
Polyclonal
Conjugate
Unconjugated
Purification
Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
Concentration
1.0 mg/mL
Formulation
Supplied in phosphate-buffered saline (without Mg²? and Ca²?), pH 7.4, containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol.
Storage
Shipped at 4°C. Upon delivery aliquot and store at -20°C. Avoid freeze/thaw cycles.
