Anti-PP2A Antibody, C subunit, clone 1D6

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 downmodulator 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 antibody recognizes PP2A catalytic subunit, Mr 36 kDa.

A 16 residue synthetic peptide (C-RGEPHVTRRTPDYFL) corresponding to amino acids 295-309 of the 36 kDa catalytic subunit of human protein phosphatase 2A (PP2A). Clone 1D6.

Epitope: a.a. 295-309

Detect PP2A using this Anti-PP2A Antibody, C subunit, clone 1D6 validated for use in IC, IP & WB.

Immunoprecipitation:
4 µg of a previous lot immunoprecipitated PP2A from 500 µg of A431 RIPA lysate. Note: This antibody has been reported not to block phosphatase activity.

Immunocytochemistry:
5-10 µg/mL of a previous lot of this antibody showed positive immunostaining for PP2A in A431 cells fixed for 10 minutes with 4% paraformaldehyde in PBS.
