Used in biomedical research to quantitatively measure RAP1A protein levels in cell lysates, tissue extracts, and biological fluids. Enables study of RAP1A involvement in cellular signaling pathways, particularly those related to cell adhesion, proliferation, and cancer progression. Widely applied in oncology and molecular biology research to assess RAP1A expression under experimental conditions, aiding in the understanding of Ras-family GTPase regulation and its role in tumor development. Suitable for use in preclinical studies investigating targeted therapies and signal transduction mechanisms.
