Used in biomedical research to quantify cyclin D1 protein levels in mouse tissue extracts or cell lysates. Helps study cell cycle regulation, particularly in cancer research where cyclin D1 overexpression is linked to tumor development. Enables researchers to assess the impact of drugs, genetic modifications, or signaling pathways on G1 phase progression in mouse models. Widely applied in immunology, oncology, and molecular biology studies involving cell proliferation and differentiation.
