Used for the quantitative measurement of creatine kinase B (CKB) activity in biological samples such as cell lysates, tissue extracts, and serum. This ELISA kit enables researchers to assess CKB levels in neuroscience research, particularly in studies related to brain injury, neurodegenerative diseases, and neuronal metabolism. It is also applied in cancer research, as CKB has been associated with tumor progression and cellular energy regulation in certain malignancies. The assay provides a reliable and sensitive method for high-throughput screening in clinical and preclinical studies.
