Anti-hnRNP A3 antibodies enable researchers to detect and measure the hnRNP A3 antigen in biological samples. This target is a reported synonym of the HNRNPA3 gene, which encodes heterogeneous nuclear ribonucleoprotein A3. This protein is known to function in RNA splicing, among other biological roles. The human version of hnRNP A3 has a canonical amino acid length of 378 residues and a protein mass of 39.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. This target antigen may also be known as epididymis secretory sperm binding protein. Indicated applications for hnRNP A3 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
