Human Protein Phosphatase 3, Regulatory Subunit 1 (PPP3R1) ELISA Kit

Calcineurin B, the calcium-binding regulatory subunit 1 of protein phosphatase 3 (PPP3R1), can be quantified in prepared human tissue homogenates using this 96-assay microplate ELISA kit from Assay Genie. The assay targets a regulatory subunit that anchors calcineurin, a serine/threonine phosphatase central to T-lymphocyte activation, NFAT transcription factor signaling, and the mechanism of immunosuppressive drugs such as cyclosporine A and tacrolimus (FK506). Investigators working on calcineurin-NFAT signaling, immune cell regulation, cardiac hypertrophy, or neuronal calcium-dependent dephosphorylation apply the kit to homogenized tissue. Each pack supplies enough wells for standard curves alongside experimental samples on a single plate. The reagents are intended for research use only and support studies of PPP3R1 expression in disease models and pharmacological investigations of immunosuppressant activity.
