Anti-NSR1 antibodies enable researchers to detect and measure the NSR1 antigen in biological samples. This target is a reported synonym of the NCL gene, which encodes nucleolin. This protein is known to function in angiogenesis and the regulation of transcription, among other biological roles. The human version of NSR1 has a canonical amino acid length of 710 residues and a protein mass of 76.6 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include C23 and C23. Some NSR1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
