Anti-B19 antibodies enable researchers to detect and measure the B19 antigen in biological samples. This target is a reported synonym of the HUNK gene, which encodes hormonally up-regulated Neu-associated kinase. This protein is known to function in intracellular signal transduction and protein phosphorylation, among other biological roles. The human version of B19 has a canonical amino acid length of 714 residues and a protein mass of 79.7 kilodaltons. It is reported to be widely expressed in many tissue types. This target antigen may also be known as hormonally up-regulated neu tumor-associated kinase. Indicated applications for B19 antibodies listed below include ELISA and Western Blot.
