Anti-IL-11 antibodies enable researchers to detect and measure the IL-11 antigen in biological samples. This target is a reported synonym of the IL11 gene, which encodes interleukin 11. This protein is known to function in B cell differentiation and cell proliferation, among other biological roles. The human version of IL-11 has a canonical amino acid length of 199 residues and a protein mass of 21.4 kilodaltons, although 2 isoforms have been identified. It is reported to be a secreted protein. Other names for this target antigen include AGIF, adipogenesis inhibitory factor, and oprelvekin. Over 60 citations in the literature describe the use of IL-11 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
