Product Overview
PP2A-α (Phospho-Y307) polyclonal antibody detects endogenous levels of PP2A-α protein only when phosphorylated at Tyr307.
Protein phosphatase type 2A (PP2A) is an essential protein serine/threonine phosphatase that is conserved in all eukaryotes. PP2A is a key enzyme within various signal transduction pathways as it regulates fundamental cellular activities such as DNA replication, transcription, translation, metabolism, cell cycle progression, cell division, apoptosis and development. The core enzyme consists of catalytic C and regulatory A (or PR65) subunits, with each subunit represented by α and β isoforms. Additional regulatory subunits belong to four different families of unrelated proteins.

Please refer to the storage conditions on the product label and datasheet. As a general best practice: upon receipt, aliquot into single-use volumes to minimize freeze-thaw cycling, which can progressively reduce antibody performance and lead to aggregation.
Validated reactivity covers Human, Rat, Mouse samples. Performance can vary across different cell lines and tissue types depending on target antigen expression levels and epitope accessibility. We recommend verifying target expression in your specific model system using a known positive control before proceeding to experimental samples.
