Used in immunological research to quantify Human B cell growth factor (BCGF) levels in biological samples such as serum, plasma, or cell culture supernatants. The ELISA kit enables researchers to study BCGF's role in B cell activation, proliferation, and differentiation in immune responses. Commonly applied in studies related to autoimmune diseases, infections, and immunodeficiency disorders. Supports high-throughput screening and biomarker discovery in clinical and preclinical research settings. Provides sensitive and specific detection, allowing accurate measurement of BCGF concentration for data analysis in immunology and biomedical research.
