Technical Data
PPP2CA, phosphorylated, Tyr307 (Protein Phosphatase 2, catalytic subunit, alpha isozyme, PP2A-alpha, PP2Ac, PP2CA, PP2Calpha, Serine/threonine-protein phosphatase 2A catalytic subunit alpha isoform)
Protein phosphatase type 2A (PP2A) is a protein serine/threonine phosphatase that controls fundamental cellular processes, including transcription, translation, metabolism, cell growth, apoptosis, and varied other signal transduction pathways. PP2A is comprised of a core enzyme, which is made up of catalytic C and regulatory A (PR65) subunits, and a secondary regulatory B subunit. This B subunit contains four different protein families. In response to EGF or insulin, it has been shown that Src phosphorylates PP2A at Tyr307, thereby inactivating PP2A.

Suitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Western Blot: 1:5000
Immunohistochemistry: 1:50
Immunocytochemistry: 1:50
Immunoprecipitation: 1:100
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
