The IFF ELISA kits listed below utilize specific antibodies for the plate-based assay of IFF in various samples. IFF is another term for the IFNB1 gene, which encodes the protein, interferon beta 1 in humans. It has been reported that IFF plays a role in adaptive immune responses and B cell differentiation, among other functions. Structurally, the IFNB1 protein is described to be 187 amino acid residues in length and 22.3 kilodaltons in mass. It is known to be a secreted protein. This protein is known to be glycosylated. Other names for this target antigen include IFB and IFN-beta. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
