Scientific Data

Western Blot Detection of Human/Mouse/Rat PP1ca antibody by Western Blot. View Larger

Detection of Human/Mouse/Rat PP1ca by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, Nb2-11 rat lymphoma cell line, and Neuro-2A mouse neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat PP1 Catalytic Subunit Monoclonal Antibody (Catalog # MAB3000) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Specific bands were detected for PP1 catalytic subunits at approximately 39 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: PP1

Protein Phosphatase 1, also known as PP1 and PPP1, is an enzyme that removes phosphate groups attached to serine or threonine residues in proteins. The holoenzyme is composed of two subunits, a catalytic subunit (PP1ca) that is highly conserved throughout evolution, and a wide variety of regulatory subunits that target the enzyme to specific subcellular compartments and proteins. The catalytic subunit is ubiquitously expressed in tissues and cell lines.
