Product Specifications

Immunogen

This protein A purified CENPQ Antibody was prepared from whole rabbit serum produced by repeated immunizations with full-length human CENPQ recombinant protein. (Uniprot: Q7L2Z9)

Reactivity Notes

A BLAST analysis of the full length sequence was used to suggest partial cross-reactivity with CENPQ based on the following percentage homologies: macaque (91%), horse (76%), bovine (74%), dog (73%), swine (71%), mouse (65%) and rat (60%). Cross-reactivity with CENPQ from other sources has not been determined.

Clonality

Polyclonal

Host

Rabbit

Isotype

IgG

Description

This product was protein A purified from monospecific antiserum by immunoaffinity chromatography using protein A coupled to agarose beads

Store vial at -20C prior to opening. Aliquot contents and freeze at -20C 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 4C as an undiluted liquid. Dilute only prior to immediate use.

Immunocytochemistry/Immunofluorescence: CENPQ Antibody [NBP1-42740] - Analysis of endogenous CENP-Q in HeLa whole cell lysate. Primary antibody was used at 1:100 followed by secondary antibody diluted 1:150. Red punctate anti-CENP-Q signal colocalizes in overlay images with green punctate anti-CREST signals at the kinetochores (attached points of sister chromatids). Visible are colocalized CENP-Q and CREST signal at various stages of the cell cycle as indicated from interphase to the end of mitosis. Nuclei are counter stained with bisbenzimide.

Background: CENPQ

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.
