Background Information
PPP1CB, also named as PP-1B, belongs to the PPP phosphatase family and PP-1 subfamily. Protein phosphatase (PP1) is essential for cell division, it participates in the regulation of glycogen metabolism, muscle contractility and protein synthesis. PPP1CB is involved in regulation of ionic conductances and long-term synaptic plasticity. This antibody is specific to PPP1CB.

Reviews
What customers say
Both reviewers gave 5-star ratings. One user found the antibody works beautifully for Western Blot and Immunofluorescence on mouse oocytes and budding yeast, though they noted it cross-reacts with both PPP1CA and PPP1CB (not PPP1CC), suggesting it is not fully specific to PPP1CB alone. The other user reported excellent performance in Western Blot at a 1:3000 dilution on colon tissue and Caco2 cells. Overall, users are satisfied with the antibody's performance across applications, with one caveat regarding isoform specificity.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Nikki (Verified Customer) (01-28-2026) | Antibody works beautifully for IIF and WB. However, it is not specific for PPP1CB as advertised. We have found it detects human PPP1CA and PPP1CB (does not detect PPP1CC) via immunoblotting of budding yeast expressing one human PPP1C isoform at a time.

Balawant (Verified Customer) (08-23-2022) | I have used this antibody for western blot in mice tissue sample (colon tissue). it is working great.
