Anti-PPP4R4 Antibody

Raised in rabbit and affinity-purified, this polyclonal IgG reagent from Antibodies.com targets the regulatory subunit PPP4R4 (Protein Phosphatase 4 Regulatory Subunit 4), a scaffolding component of the PP4 phosphatase complex implicated in DNA damage response signaling and spermatogenesis. Validated for Western blot detection of mouse samples, the unconjugated antibody is supplied as 100 µl of liquid and supports immunoblotting workflows that probe phosphatase regulatory networks in murine systems. The polyclonal IgG format offers broader epitope coverage than a monoclonal reagent, allowing recognition of multiple regions of the target protein in cell lysates and tissue homogenates. Applications extend to studies of PP4 complex assembly, germ cell differentiation, and genome stability pathways, where detection of endogenous PPP4R4 expression helps elucidate its role in checkpoint control and male germ line development.
