Used in research settings to quantitatively measure Cyclin-D1 protein levels in rat biological samples such as cell lysates, tissue homogenates, and serum. This kit is particularly useful in studies related to cell cycle regulation, cancer progression, and proliferative diseases, as Cyclin-D1 plays a key role in the transition from G1 to S phase. It enables high-throughput analysis with high sensitivity and specificity, making it suitable for investigating the effects of drugs, genetic modifications, or environmental factors on cell proliferation pathways in rat models.
