Human ATPase, Na+/K+ Transporting Beta 1 Polypeptide (ATP1b1) ELISA Kit

Quantify the β1 regulatory subunit of the Na⁺/K⁺-ATPase with this human-specific immunoassay from Assay Genie. ATP1b1 (ATPase Na⁺/K⁺ Transporting Beta 1 Polypeptide) is essential for assembly, maturation, and stable plasma-membrane insertion of the catalytic α subunit, and changes in its expression are studied in cardiac electrophysiology, neuronal signalling, renal tubular function, and epithelial ion transport research.

The assay accepts serum samples, plasma samples, tissue homogenates, and cell lysates, broadening its utility across in vitro culture supernatants and primary tissue preparations. Each kit provides reagents for 96 individual determinations in a microplate format and produces an absorbance-based readout compatible with standard laboratory plate readers.

Recommended applications include cardiovascular disease research where altered Na⁺/K⁺-pump stoichiometry contributes to contractile dysfunction, neuroscience studies of cardiac glycoside signalling pathways, and investigations of ATP1b1 as a docking receptor exploited by certain viral entry mechanisms. Reagents should be stored refrigerated and the substrate solution protected from light to preserve signal stability across the full run.
