Used in biomedical research to detect and quantify levels of human Activin A (AF) protein in biological samples such as serum, plasma, and cell culture supernatants. The kit is commonly applied in studies related to reproductive health, inflammation, immune regulation, and cancer. It enables researchers to assess Activin A's role in cellular differentiation, tissue development, and disease progression. Due to its high sensitivity and specificity, the ELISA kit supports accurate measurement in clinical diagnostics and therapeutic monitoring within laboratory settings. Not intended for use in diagnostic procedures in humans.
