Background

53BP1 (p53 binding protein 1) plays a key role in response to DNA damage, checkpoint signaling during mitosis and enhancing TP53-mediated transcriptional activation. Originally identified as p53's transcriptional enhancing partner, 53BP1 now has been established as a substrate for ATM (ataxia telangiectasia mutated) signaling and that it relocalizes to discrete foci overlapping with gamma H2AX (phosphorylated histone H2AX); demarcating DNA double strand breaks (DSBs) sites following exposure to radiation. 53BP1 functions downstream of gamma H2AX-dependent hierarchy of proteins that collectively establish IRIF (ionizing radiation induced foci) at DSBs; this hierarchy includes Mre11/Rad50/NBS1 (MRN complex), ATM, MDC1, RNF8, RNF168 and HERC2. With the exception of ATM, whose function to generate gamma H2AX may be partially compensated by the activity of DNA-PK (DNA-dependent kinase), all of these proteins are physically and functionally required to recruit 53BP1 to the DSB site. Briefly, this process involves DSB recognition by MRN, ATM activation, gamma H2AX-formation, MDC1-recruitment, MRN-retention (leading to further ATM-activation and gamma H2AX spreading) and RNF8/RNF168/HERC2-mediated histone H2A and H2AX mono and poly-ubiquitination.

reviewed by: Anonymous IHC Mouse 07/14/2010

Summary

• Application: Immunohistochemistry
• Sample Tested: Mouse thymocytes
• Species: Mouse
• Comments: I needed to localize DSB repair at a single locus, so IHC was combined with DNA FISH. Many other antibodies failed, as DNA FISH requires heating the cells to 80 degrees C which denatures most proteins. This anti-53BP1 antibody resulted in discrete, bright foci regardless of FISH hybridization.

FAQs for 53BP1 Antibody (NB100-304). (Showing 1 - 4 of 4 FAQs).

1. We're looking for anti53BP1 antibody covalently labeled with a fluorofor preferabley Cy3. Do you make it?
   • We sell 53BP1 antibodies available conjugated to DyLight 488, 550 (very similar in spectrum to Cy3) and 650. You may also purchase the unlabeled antibodies and conjugate them to the fluorophores of your choice. The catalog numbers that you may be interested in are: NB100-904R, NB100-304R, NB100-305R.
2. Hello I want to ask you for an advice in case of antibodies. In our research we focus on DNA repair foci and use your Novus antibodies for phosphorylated histone H2AX (monoclonal mouse) and protein 53BP1(polyclonal rabbit). Now we want to use antobody for phosphorylated 53BP1 protein to increase specifity and I want to ask you which from your NOVUS antibodies will be the best for us.
   • We currently stock just one antibody to phosphorylated 53BP1, which you can see at the following link: NB100-1803. This is guaranteed for detection of 53BP1 (pSer25) in human and mouse samples by WB, FLOW, ICC/IF,IHC-P, IP and PLA. As this antibody is a rabbit polyclonal, you would be unable to stain for both 53BP1 and its phosphorylated isoform in the same sample, unless you used an antibody from a different host for detection of total 53BP1 or used directly conjugated primaries. Our mouse monoclonal to 53BP1, with catalogue number NBP2-25028, is validated for detection of the human protein by WB, FLOW and IHC. Unfortunately we do not currently stock any other antibodies to phosphorylated 53BP1.
3. What is the recommended pH of sodium citrate for the 53bp1 antibody (NB100-304)?
   • I have checked our notes for use of this antibody in IHC, and they say: 1:500 to 1:2,000. Epitope retrieval with citrate buffer pH6.0 is recommended for FFPE tissue sections.
4. Is possible to know the exact sequence of the epitope used?
   • Unfortunately I am unable to disclose the sequence of this antibody due to proprietary restrictions. At the site recognized by NB100-304, the reference sequences are too divergent to expect NB100-304 to bind to either Bovine or Little Brown Bat. Regarding Mouse Homology, 30/34 sites of the immunogen are homologous Human - 100% homologous.
