Product Overview
This rabbit polyclonal antibody recognizes serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit delta isoform (gene PPP2R5D) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry, immunoprecipitation and ELISA. The predicted molecular weight is 70.0 kDa, and the supplier reports an observed band at about 74 kDa.
PPP2R5D (B56δ) is a B′-family regulatory subunit of protein phosphatase 2A that directs its substrate specificity and location. It is highly expressed in brain, and de novo PPP2R5D variants cause a neurodevelopmental disorder, making it a focus of PP2A studies in neurons.

Immunogen
Recombinant human PPP2R5D fragment (Arg91–Leu602), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit delta isoform in the cytoplasm and nucleus. Tissue expression noted by UniProt (human): Isoform Delta-2 is widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
