Used in biomedical research to quantify choline kinase 1 (CK-1) protein levels in human biological samples such as serum, plasma, and cell lysates. This ELISA kit enables researchers to study CK-1's role in cellular processes including phospholipid metabolism, cell membrane synthesis, and signal transduction. It is particularly valuable in cancer research, as CK-1 is often overexpressed in tumors and linked to cell proliferation and oncogenesis. The kit supports the investigation of CK-1 as a potential biomarker for disease progression and response to therapy in conditions like breast, lung, and colorectal cancers. It is also used in drug development to assess the efficacy of kinase inhibitors targeting choline metabolism pathways.
