Anti-UPK1 antibodies enable researchers to detect and measure the UPK1 antigen in biological samples. This target is a reported synonym of the UPK1B gene, which encodes uroplakin 1B. This protein is known to function in epithelial cell differentiation, among other biological roles. The human version of UPK1 has a canonical amino acid length of 260 residues and a protein mass of 29.6 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the urinary bladder, stomach, and gallbladder. Other names for this target antigen include TSPAN20, TSPAN20, and UPIB. Indicated applications for UPK1 antibodies listed below include ELISA, Flow Cytometry, Western Blot, Immunofluorescence, and Immunohistochemistry.
