Anti-NOP1 antibodies enable researchers to detect and measure the NOP1 antigen in biological samples. This target is a reported synonym of the FBL gene, which encodes fibrillarin. This protein is known to function in osteoblast differentiation and rRNA processing, among other biological roles. The human version of NOP1 has a canonical amino acid length of 321 residues and a protein mass of 33.8 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. NOP1 is a member of the Fibrillarin protein family. Some NOP1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
