Anti-lupin antibodies enable researchers to detect and measure the lupin antigen in biological samples. This target is a reported synonym of the NT5C3A gene, which encodes 5'-nucleotidase, cytosolic IIIA. This protein is known to function in viral immune response, among other biological roles. The human version of lupin has a canonical amino acid length of 336 residues and a protein mass of 37.9 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the ER and cytoplasm of cells. Other names for this target antigen include NT5C3, P5'N-1, and P5N-1. Indicated applications for lupin antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
