Used in biomedical research to quantify Ki-67 protein levels in rat tissue samples or cell lysates. This ELISA kit enables researchers to assess cell proliferation in studies related to cancer, toxicology, regenerative medicine, and drug development. It is particularly valuable in evaluating tumor growth rates, monitoring responses to therapeutic agents, and investigating mechanisms of cell cycle regulation in rodent models. The assay provides a sensitive and specific colorimetric readout, allowing high-throughput analysis of multiple samples. Commonly used in preclinical research and academic laboratories.
