Applications
Our Abpromise guarantee covers the use of ab214 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| Application | Abreviews | Notes |
|---|---|---|
| Flow Cyt | Use 1-2µg for 106 cells. ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody. |
|
| ICC/IF | 1/200 - 1/500. Wash cells with PBS, then wash with PBS containing 0.5% Triton X-100 and fix for 5 min with PBS containing 3% paraformaldehyde. Block cells for 1 h in PBS containing 15% fetal bovine serum (see Robinson et al). | |
| IHC-Fr | 1/200. | |
| WB | Use a concentration of 1 - 5 µg/ml. Detects a band of approximately 79 kDa (predicted molecular weight: 79 kDa). (see Robinson et al). | |
| IP | Use a concentration of 1 - 5 µg/ml. (for normal lymphoblastoid cell lines). | |
| IHC-P | Use at an assay dependent concentration. |
Target
-
FunctionComponent of the MRN complex, which plays a central role in double-strand break (DSB) repair, DNA recombination, maintenance of telomere integrity and meiosis. The complex possesses single-strand endonuclease activity and double-strand-specific 3'-5' exonuclease activity, which are provided by MRE11A. RAD50 may be required to bind DNA ends and hold them in close proximity. This could facilitate searches for short or long regions of sequence homology in the recombining DNA templates, and may also stimulate the activity of DNA ligases and/or restrict the nuclease activity of MRE11A to prevent nucleolytic degradation past a given point. The complex may also be required for DNA damage signaling via activation of the ATM kinase. In telomeres the MRN complex may modulate t-loop formation.
-
Involvement in diseaseDefects in MRE11A are a cause of ataxia telangiectasia-like disorder (ATLD) [MIM:604391]. ATLD is a disease with the same clinical feature than ataxia-telangiectasia but with a somewhat milder clinical course.
-
Sequence similaritiesBelongs to the MRE11/RAD32 family.
-
Post-translational
modificationsPhosphorylated upon DNA damage, probably by ATM or ATR. -
Cellular localizationNucleus. Localizes to discrete nuclear foci after treatment with genotoxic agents.

Tissue was fixed with paraformaldehyde for 3 hours, permeabilized with 0.1% Triton X-100 and blocked with 5% serum for 1 hour at 23°C. Samples were incubated with primary antibody (1/200 in 3% BSA + 0.1% Triton X-100 in TBS buffer) for 12 hours at 4°C. An undiluted HRP-conjugated goat anti-mouse IgG polyclonal was used as the secondary antibody.
