Human Casein kinase II subunit beta (CSNK2B) ELISA Kit

From Assay Genie, this Sandwich ELISA Kit provides quantitative measurement of human Casein Kinase II subunit beta (CSNK2B) using a colorimetric detection method. Validated for use with human serum, plasma, cell culture supernatant, tissue homogenates, and other biological fluids, the kit supports research into cancer and the role of CSNK2B in disease biology. It is intended for research use only.

Performance characteristics include a detection range of 78–5000 pg/mL and a sensitivity of 33 pg/mL. Intra-assay precision is 4.5% CV and inter-assay precision is 8.5% CV. Spike-and-recovery testing in serum averaged 101% (range 95–107%) and in plasma averaged 103% (range 97–109%). The assay is specific for natural and recombinant human CSNK2B, which is also known by the synonyms Phosvitin, Protein G5a, CK II beta, CK2N, and G5A.

CSNK2B is a regulatory subunit of Casein Kinase II, a ubiquitous protein kinase involved in cellular processes such as cell growth, proliferation, and apoptosis. Dysregulation of CSNK2B has been linked to cancer, neurodegenerative disorders, and cardiovascular disease, making it a focus of biomarker and therapeutic development research.
