These B19 ELISA kits are immunodetection tools for measuring the levels of B19 in biological samples. B19 is an alias of the human HUNK gene, which encodes the protein, hormonally up-regulated Neu-associated kinase. Notably, B19 is known to play a role in intracellular signal transduction and protein phosphorylation, among other functions. The HUNK protein is described to be 714 amino acid residues in length and 79.7 kilodaltons in mass. Other names for this target antigen include hormonally up-regulated neu tumor-associated kinase.
