Anti-methyl-PP2A Antibody, C subunit, clone 2A10

Type 2 protein serine/threonine phosphatase (PP2A) is a trimer composed of a catalytic C subunit and two regulatory (A and B) subunits; many isoforms for the A and B subunits have been found. PP2A has a high specific activity against the α subunit of phosphorylase kinase and is insensitive to Inhibitor-2. PP2A is distinguishable from PP2B/Calcineurin and PP2C by its partial activity in the absence of divalent cations, and by its high sensitivity to inhibition by okadaic acid. It is also thought to be the principal down-modulator of serine/threonine kinase cascades. PP2B requires Ca2+/calmodulin for activity, and is an activator of NFAT transcription factors. PP2C requires Mg2+, but is insensitive to okadaic acid, microcystin LR, or the calmodulin inhibitor trifluoperazine.

This Anti-methyl-PP2A Antibody, C subunit, clone 2A10 is validated for use in WB for the detection of methyl-PP2A. Exhibits some reactivity with methyl-PP4 and slight reactivity with methyl-PP6.

Recognizes the methylated form of PP2A, catalytic subunit. Exhibits some reactivity with methyl-PP4 and slight reactivity with methyl-PP6.

Format: Purified

Protein G Purified

Purified mouse monoclonal in buffer containing 0.1M Tris-Glycine (pH 7.4), 150mM NaCl and 0.05% sodium azide.

Stable for 1 year at 2-8°C from date of receipt. For maximum recovery of product, centrifuge the vial prior to removing the cap.

Control
Lysates from a yeast wild type strain (strain lacking the methyltransferase, delta PPM1) and a strain lacking the methylestrase, delta PPE1.

Evaluated by western blot on lysates from a yeast wild type strain (strain lacking the methyltransferase, delta PPM1) and a strain lacking the methylestrase, delta PPE1.

Western Blot Analysis: 1-5 µg/mL of this antibody detected the methylated form of PP2A catalytic subunit in yeast lysates lacking the methylestrase (increased methylation). Treatment of the blot with 0.2 M NaOH will demethylate proteins, thus eliminating detection of PP2A.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
