IFNA21 ELISA kits are immunoassay tools for the measurement of the protein interferon alpha 21, which is encoded by the IFNA21 gene in humans. Functionally, this protein is known to be involved in adaptive immune responses and B cell differentiation. The canonical protein structure is reported to have an amino acid length of 189 residues, a mass of 21.7 kDa, and is a member of the Alpha/beta interferon protein family. It is known to be secreted. Other alias names for this target include LeIF F, leIF-F, IFN-alpha-21, interferon alpha-F, leukocyte interferon protein, and IFN-alphaI.
The detection range for different IFNA21 ELISA kits can vary, with some assays measuring target concentrations as low as 1.37 pg/mL and as high as 2000 ng/L. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
