Used in biomedical research to quantitatively measure levels of Cyclin-E protein in human cell lysates, serum, or plasma. This kit is particularly useful in studies related to cell cycle regulation, as Cyclin-E plays a critical role in the transition from G1 to S phase. Researchers apply it in cancer studies, especially in investigations of uncontrolled cell proliferation, tumorigenesis, and diagnostic biomarker development. The assay helps assess Cyclin-E overexpression, which is associated with various malignancies including breast, ovarian, and esophageal cancers. It is also used in pharmacological research to evaluate the impact of cell cycle-targeting drugs.
