Used extensively in immunological research as a standard protein in assays such as ELISA and Western blotting to calibrate instruments and validate protocols. It serves as a blocking agent to prevent non-specific binding in immunoassays, ensuring accurate detection of target proteins. Additionally, it is employed in the production of antibodies, where it acts as an immunogen to generate specific immune responses in laboratory animals. In diagnostic labs, it is utilized as a control material to verify the performance of diagnostic kits and equipment. Its role in vaccine development includes being a component in formulations to enhance immune responses. Furthermore, it is applied in cell culture studies to provide a protein-rich environment that supports cell growth and stability.
