Used in biomedical research to detect and quantify smooth muscle alpha-actinin (smActinin-α) in tissue samples or cell lysates. This ELISA kit enables researchers to study smooth muscle cell differentiation, vascular injury responses, and diseases involving smooth muscle dysfunction such as atherosclerosis, hypertension, and gastrointestinal motility disorders. It is commonly applied in studies related to cardiovascular biology, regenerative medicine, and drug development where accurate measurement of smActinin-α levels helps assess smooth muscle phenotype and function.
