Anti-CENP-Q Antibody

This antibody is suitable for Cancer, Immunology and Nuclear Signaling research. Cenp-Q (also known as centromere protein Q or CENPQ) is a nuclear/centromeric protein that is one of the critical components that constitutes the CENP-O complex at the kinetochores and appears to stabilize PBIP1/CENP-U (50) /MLF1IP in the complex. This complex is important for proper recruitment of polo-like kinase 1 (Plk1) to the mitotic kinetochores. A failure in this process results in improper microtubule attachment to the kinetochores and chromosome missegregation that ultimately lead to aneuploidy.

This protein A purified antibody was prepared from whole rabbit serum produced by repeated immunizations with full-length human CENP-Q recombinant protein.

This product was protein A purified from monospecific antiserum by immunoaffinity chromatography using protein A coupled to agarose beads. This antibody is specific for human CENP-Q protein. A BLAST analysis of the full length sequence was used to suggest partial cross-reactivity with CENP-Q based on the following percentage homologies: macaque (91%), horse (76%), bovine (74%), dog (73%), swine (71%), mouse (65%) and rat (60%) . Cross-reactivity with CENP-Q from other sources has not been determined.

Component of the CENPA-CAD (nucleosome distal) complex, a complex recruited to centromeres which is involved in assembly of kinetochore proteins, mitotic progression and chromosome segregation. May be involved in incorporation of newly synthesized CENPA into centromeres via its interaction with the CENPA-NAC complex.

Store vial at -20°C prior to opening. Aliquot contents and freeze at -20°C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4°C as an undiluted liquid. Dilute only prior to immediate use. Expiration date is one (1) year from date of opening.

This protein A purified antibody has been tested for use in ELISA, immunofluorescence microscopy and western blotting. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 26-31 kDa in size corresponding to human CENP-Q by western blotting in the appropriate cell lysate or extract.

Nucleus. Chromosome, centromere. Localizes exclusively in the centromeres. The CENPA-CAD complex is probably recruited on centromeres by the CENPA-NAC complex.
