Used in biomedical research to quantify myosin light chain (MLC) levels in biological samples such as cell lysates, tissue homogenates, and serum. This kit is essential for studying muscle contraction, smooth muscle regulation, and cellular motility. It is widely applied in cardiovascular research to assess MLC phosphorylation states associated with vascular tone and hypertension. Also used in cancer research to investigate cell migration and metastasis, as MLC plays a role in cytoskeletal dynamics. The assay supports high-throughput screening and provides a reliable, sensitive method for monitoring MLC expression in experimental models of disease and drug response.
