Anti-Neurokinin A antibodies enable researchers to detect and measure the Neurokinin A antigen in biological samples. This target is a reported synonym of the TAC1 gene, which encodes tachykinin precursor 1. This protein is known to function in cell to cell signaling and chemical synaptic transmission, among other biological roles. The human version of Neurokinin A has a canonical amino acid length of 129 residues and a protein mass of 15 kilodaltons, although 4 isoforms have been identified. It is reported to be a secreted protein that is notably expressed in the small intestine, rectum, hippocampus, duodenum, and cerebral cortex. Other names for this target antigen include Hs.2563, NK2, and NKNA. Immunohistochemistry is a widely used application for the Neurokinin A antibodies listed below. In addition, Western Blot is also a common application.
