Used in biomedical research to quantitatively measure levels of CDKN3 protein in human cell or tissue samples. This ELISA kit helps study the role of CDKN3 in cell cycle regulation, particularly its involvement in controlling cyclin-dependent kinases. It is widely applied in cancer research to investigate tumor progression, as CDKN3 expression is often altered in various malignancies. The kit enables researchers to assess CDKN3 as a potential biomarker for diagnosis or prognosis in diseases like liver, breast, or lung cancer. It is also used in molecular biology studies exploring cell proliferation, apoptosis, and response to therapeutic agents.
