This antibody reacts with CD37 antigen (Human), 40-52 kDa glycoprotein. IPO-24 reacts with Human B cell lines Daudi, Raji, Namalva, Ramos and CABIL, whereas T cell lines CEM, Molt-4, Jurkat, MT-4, H9 and non-lymphoid cell lines MeWo and A-431 are not labelled. IPO-24 stains B cell follicles and the most strongly labelled elements are mantle zone lymphoid cells. Neutrofils, macrophages, thymocytes and dendritic reticulum cells are negative.

Immunogen
IPO-24 was generated after immunization of BALB/c mice with spleen cells of a patient with hairy cell leukemia. Mice splenocytes were fused with the P3-X63-Ag8.653 mouse myeloma cell line.
CD37 is a membrane protein of the tetraspanin superfamily, which includes CD9, CD53, CD81, and the R2 antigen among others. Many of these molecules are expressed on leukocytes and have been implicated in signal transduction, cell to cell interactions, and cellular activation and development. The antigen CD37 defined by IPO-24 is B lineage restricted and is strongly expressed throughout B cell ontogeny from pre-B cells untill the plasmoblasts. CD37 is an extensively glycosylated molecule and usually two and sometimes three N-linked carbohydrate chain are attached to the protein. Synonyms: Leukocyte antigen CD37, TSPAN26, Tetraspanin-26
