Human PHKB ELISA Kit (HUFI07238)

This ELISA kit from Assay Genie provides a colorimetric immunoassay for quantitative detection of phosphorylase kinase regulatory subunit beta (PHKB) in human specimens, read on a standard microplate reader. The PHKB gene encodes the beta regulatory subunit of phosphorylase kinase, a key enzyme complex in glycogen metabolism that activates glycogen phosphorylase in response to hormonal and calcium signaling. Mutations in PHKB cause glycogen storage disease type IXb, a metabolic disorder characterized by hepatomegaly and mild muscle weakness, making accurate protein-level measurement valuable for studies of hepatic glycogenolysis, muscle energy metabolism, and related signaling pathways.

Reactive with human samples, the kit supports research workflows in metabolic disease, endocrinology, and enzymology laboratories. Reconstituted reagents and working standards should be refrigerated and protected from repeated freeze-thaw cycles to preserve activity. Each kit is supplied as a single use box of components sufficient for one microplate run, with a shelf life suitable for routine laboratory use.
