Product Overview
Polyclonal Antibodies
Protein phosphatase 2A is one of the four major Ser/Thr phosphatases and is implicated in the negative control of cell growth and division. Protein phosphatase 2A holoenzymes are heterotrimeric proteins composed of a structural subunit A, a catalytic subunit C, and a regulatory subunit B. The regulatory subunit is encoded by a diverse set of genes that have been grouped into the B/PR55, B'/PR61, and B''/PR72 families. These different regulatory subunits confer distinct enzymatic specificities and intracellular localizations to the holozenzyme. The product of this gene belongs to the B' family.

This antibody has been validated for IF/ICC. Always refer to the product datasheet for recommended dilution ranges and appropriate positive control samples for each application type.
Validated reactivity has been confirmed for Human, Mouse. Cross-reactivity with additional species may exist based on sequence homology but has not been confirmed by the manufacturer. For unlisted species, we recommend running a preliminary validation experiment.
This antibody was raised in Rabbit. For indirect detection (WB, IHC, IF), select an anti-Rabbit secondary antibody that matches the isotype. For direct detection, check the variant selector for conjugated formats. Confirm secondary antibody compatibility before ordering.

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, 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.
