Anti-PPP1R3A Antibody

PPP1R3A (Protein Phosphatase 1 Regulatory Subunit 3A) is the muscle-specific glycogen-targeting subunit of protein phosphatase 1, and this rabbit polyclonal antibody is raised against it for western blot detection in human and mouse samples. As a regulatory scaffold that localizes PP1 to glycogen particles in skeletal muscle, PPP1R3A plays a pivotal role in glycogen synthesis downstream of insulin signaling, with relevance to research on insulin resistance, type 2 diabetes, and metabolic regulation in striated muscle tissue.

Provided by Antibodies.com as an unconjugated IgG of polyclonal clonality, the reagent is supplied in a 200 µl vial and is intended for research use only. Refrigerated storage is recommended, and aliquoting upon receipt is advised to limit repeated freeze-thaw cycles. The unconjugated format leaves the antibody free for downstream conjugation to HRP, biotin, or fluorophores as required by individual western blot workflows.
