Used in biomedical research to quantify proliferative cell nuclear antigen (PCNA) levels in cell lysates, this ELISA kit enables assessment of cell proliferation activity. It is widely applied in cancer research to study tumor cell growth and evaluate the effectiveness of anti-cancer therapies. The kit supports investigation in DNA repair, cell cycle regulation, and tissue regeneration studies by providing a reliable measure of proliferating cells in various experimental models. Its high specificity allows researchers to distinguish active proliferation from background cellular signals in both in vitro and in vivo samples.
