Used in life science research to quantitatively measure mouse activin A protein levels in biological samples such as cell culture supernatants, serum, and plasma. This ELISA kit is particularly useful in studies related to cell differentiation, reproductive biology, inflammation, and immune regulation. It enables researchers to monitor activin A expression in mouse models of disease, including cancer, fibrosis, and metabolic disorders, supporting the development and evaluation of targeted therapies. The assay provides high specificity and sensitivity, making it suitable for detecting low concentrations of activin A in complex matrices.
