  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

CENPQ antibody was raised against this protein A purified antibody was prepared from whole rabbit serum produced by repeated immunizations with full-length human CENP-Q recombinant protein.
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.
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 kD in size corresponding to human CENP-Q by western blotting in the appropriate cell lysate or extract.


0.02 M potassium phosphate, 0.15 M sodium chloride, pH 7.2, 0.01% sodium azide, sterile filtered
Short term 4°C, long term aliquot and store at -20°C, avoid freeze thaw cycles.
For research use only.

CENPQ Antibody, C6orf139 Antibody, Centromere protein Q Antibody, CENP-Q Antibody

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.


Anti-CENP-Q Antibody - Immunofluorescence Microscopy. Immunofluorescence microscopy using protein A purified anti-CENP-Q antibody shows detection 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.

Western blot

Western blot
Anti-CENP-Q Antibody - Western Blot. Western blot of protein A purified anti-CENP-Q antibody shows detection of endogenous CENP-Q in a HeLa whole cell lysate (lane 1, arrowhead). The blot was incubated for 1.5 hours at room temperature using the primary antibody diluted to 0.5ug/mL, followed by washes and incubation with to the secondary antibody. Lane 1: Lysates from HeLa cells transfected with control sh-virus. Lane 2: Lysates from HeLa cells transfected with Cenp-Q sh-virus. Personal Communication, Kyung S. Lee, CCR-NCI, Bethesda, MD.
