Anti-UI antibodies enable researchers to detect and measure the UI antigen in biological samples. This target is a reported synonym of the UCN gene, which encodes urocortin. This protein is known to function in GPCR signaling pathways and inflammatory response pathways, among other biological roles. The human version of UI has a canonical amino acid length of 124 residues and a protein mass of 13.5 kilodaltons. It is reported to be a secreted protein that is widely expressed in many tissue types. Other names for this target antigen include UCN1 and UROC. Immunohistochemistry is a widely used application for the UI antibodies listed below. In addition, ELISA is also a common application.
