Rabbit Anti-CENP-Q (Centromere Protein Q)

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.

Applications
Suitable for use in Immunofluorescence, ELISA and Western Blot. Other applications not tested.
Recommended Dilution
Immunofluorescence: 1:100-1:500 ELISA: 1:20,000–1:30,000 Western Blot: 1:2,000-1:2,500 Optimal dilutions to be determined by the researcher.
Storage and Stability
May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Immunogen
Full-length human CENP-Q recombinant protein.
Form
Supplied as a liquid in PBS, pH 7.2, 0.01% sodium azide.
Purity
Purified by immunoaffinity chromatography.
Specificity
Species Sequence Homology: macaque(91%), horse(76%), bovine(74%), dog(73%), swine (71%), mouse(65%) and rat(60%).

Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
