Used in immunological research and therapeutic development targeting Fc gamma receptor IIa (CD32a), this reference antibody serves as a critical tool for studying antibody-dependent cellular phagocytosis (ADCP) and immune complex signaling. It is employed in flow cytometry, immunohistochemistry, and functional assays to characterize immune cell populations, particularly monocytes, macrophages, and neutrophils. Due to its high specificity, it supports the development and validation of biologics, including monoclonal antibodies, by assessing Fc receptor binding and downstream immune activation. It is also utilized in quality control during biosimilar development and in evaluating receptor occupancy in preclinical studies.
