Used in biomedical research to measure GTPase activating protein (GAP) levels in human samples, this ELISA kit enables the quantification of GAP activity in cell lysates, serum, or plasma. It is widely applied in signal transduction studies, particularly in pathways involving Ras and other small GTPases linked to cell growth, differentiation, and cancer progression. Researchers use it to assess how regulatory proteins influence GTPase function in normal and diseased states. The kit supports high-throughput screening in drug development and helps investigate molecular mechanisms in neurodegenerative diseases, cardiovascular conditions, and immune disorders.
