Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase.

Our Abpromise guarantee covers the use of ab70822 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
WB: 1/1000 - 1/10000. Detects a band of approximately 100 kDa (predicted molecular weight: 80 kDa).
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionUbiquitin-binding protein that specifically recognizes and binds 'Lys-63'-linked ubiquitin. Plays a central role in the BRCA1-A complex by specifically binding 'Lys-63'-linked ubiquitinated histones H2A and H2AX at DNA lesions sites, leading to target the BRCA1-BARD1 heterodimer to sites of DNA damage at double-strand breaks (DSBs). The BRCA1-A complex also possesses deubiquitinase activity that specifically removes 'Lys-63'-linked ubiquitin on histones H2A and H2AX. Also weakly binds monoubiquitin but with much less affinity than 'Lys-63'-linked ubiquitin. May interact with monoubiquitinated histones H2A and H2B; the relevance of such results is however unclear in vivo. Does not bind Lys-48'-linked ubiquitin. May indirectly Act as a transcriptional repressor by inhibiting the interaction of NR6A1 with the corepressor NCOR1.
Tissue specificityExpressed in testis, ovary, thymus and heart. Expressed in germ cells of the testis.
Sequence similaritiesBelongs to the RAP80 family.
Contains 2 UIM (ubiquitin-interacting motif) repeats.
DomainThe UIM-linker region between the 2 UIM repeats determines the selectivity for 'Lys-63'-linked ubiquitin. The length of the linker is important. The linker reduces the flexibility between the UIM repeats and promotes high-affinity and linkage-selective interactions.
The Abraxas-interacting region (AIR) mediates the interaction with FAM175A/Abraxas.
Phosphorylated upon DNA damage by ATM or ATR.
Cellular localizationNucleus. Localizes at sites of DNA damage at double-strand breaks.

All lanes : Anti-RAP80 antibody (ab70822) at 1 µg/ml
Lane 1 : HeLa whole cell lysate at 15 µg
Lane 2 : HeLa whole cell lysate at 5 µg
Lane 3 : 293T whole cell lysate at 50 µg
Predicted band size: 80 kDa
Observed band size: 100 kDa why is the actual band size different from the predicted?
Additional bands at: 300 kDa, 65 kDa, 80 kDa. We are unsure as to the identity of these extra bands.
Detection of Human RAP80 by Immunoprecipitation in Whole cell lysate from HeLa cells (1 mg for IP, 20% of IP loaded), using ab70822 at 3 µg/mg lysate for IP and at 1 µg/ml for subsequent Western blot detection.
