Used in immunological research to detect and quantify immunoglobulin heavy chain (IgH) in biological samples. Commonly applied in studies related to B-cell development, antibody production, and immune response monitoring. Supports research in autoimmune diseases, infectious diseases, and cancer by enabling measurement of IgH levels in serum, plasma, or cell culture supernatants. Widely used in preclinical studies and diagnostic development due to its sensitivity and specificity.
