Used in biomedical research to quantitatively measure Cyclin-D3 protein levels in human cell or tissue samples. This kit is particularly applied in cancer studies, as Cyclin-D3 plays a key role in cell cycle regulation and is often dysregulated in tumors. Researchers use it to investigate cell proliferation mechanisms, assess the impact of therapeutic agents on cell cycle proteins, and explore biomarkers in diseases like lymphoma and breast cancer. The assay supports high-throughput analysis in clinical and experimental settings, enabling accurate, sensitive detection of Cyclin-D3 concentrations in serum, plasma, and cell lysates.
