Used in immunological research to detect and quantify surface immunoglobulins expressed on human B cells. This kit enables the study of B cell activation, differentiation, and maturation in conditions such as autoimmune diseases, infections, and B cell malignancies. It is also applied in monitoring immune responses and evaluating the effectiveness of therapeutic interventions targeting B cell populations. The assay supports high-throughput analysis in clinical and research laboratories focused on immunophenotyping and immune system function.
