Anti-IL-3 antibodies enable researchers to detect and measure the IL-3 antigen in biological samples. This target is a reported synonym of the IL3 gene, which encodes interleukin 3. This protein is known to function in cell to cell signaling and immune response pathways, among other biological roles. The human version of IL-3 has a canonical amino acid length of 152 residues and a protein mass of 17.2 kilodaltons. It is reported to be a secreted protein. Other names for this target antigen include MCGF, MULTI-CSF, and P-cell stimulating factor. Over 110 citations in the literature describe the use of IL-3 antibodies in research. ELISA is a widely used application for these antibodies. Western Blot and Immunohistochemistry are also common applications.
