Used in biomedical research to quantify active RhoA-GTP levels in cell lysates, this ELISA kit enables the study of RhoA signaling pathways involved in cytoskeletal regulation, cell migration, and proliferation. It is widely applied in cancer research to investigate tumor cell invasion and metastasis mechanisms. The kit supports drug development studies by assessing the impact of therapeutic compounds on RhoA activation. It is also utilized in cardiovascular and neurological research where RhoA activity influences vascular tone and neurite retraction. High sensitivity and specificity allow reliable detection in small sample volumes, making it suitable for high-throughput screening and mechanistic studies in molecular and cellular biology.
