Detection of Human PP1 alpha by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, CHP-100 human neuroblastoma cell line, and HepG2 human hepatocellular carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Human PP1 alpha Catalytic Subunit Monoclonal Antibody (Catalog # MAB6105) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, recombinant human PP1 alpha, recombinant human PP1 beta, and recombinant human PP1 gamma (5 ng/lane) were included. A specific band was detected for PP1 apha at approximately 39 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

Background: PP1 alpha

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 that is highly conserved throughout evolution, and a wide variety of regulatory subunits that target the enzyme to specific subcellular compartments and proteins. Three isoforms of the catalytic subunit are ubiquitously expressed in tissues and cell lines: PP1 alpha, PP1 beta and PP1 gamma.
