Anti-CCNB1 antibodies are used in the immunodetection of the protein cyclin B1. In humans, the canonical protein has a reported length of 433 amino acid residues and a mass of 48.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Cyclin protein family, ccnb1 is known to be important for the control of the cell cycle at the G2/M (mitosis) transition. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include CCNB and G2/mitotic-specific cyclin-B1. CCNB1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Over 1600 citations in the literature describe the use of ccnb1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
