ATM (Ataxia Telangiectasia Mutated)

Reacts with Breast Carcinomas. Ataxia telangiectasia (AT) (ATM - for AT mutated) is a rare genetic multisystem recessive disorder. Recombinant ATM protein phosphorylates p53 on serine 15 near the N-terminus, thereby contributing to the activation and stabilization of p53 during the IR.

- Western Blotting (Not suitable)
- Immunohistology (Formalin/paraffin)(Use Ab at 1-2µg/ml for 30 min at RT)
- Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 min.

200ug/ml of antibody purified from ascites fluid by Protein G chromatography. Prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide. Also available without BSA and azide at 1mg/ml.

Refrigerate at 4°C. Do not freeze.

Material Safety Data:
This product is not licensed or approved for administration to humans or to animals other than the experimental animals. Standard Laboratory Practices should be followed when handling this material. The chemical, physical, and toxicological properties of this material have not been thoroughly investigated. Appropriate measures should be taken to avoid skin and eye contact, inhalation, and ingestion. The material contains 0.09% sodium azide as a preservative. Although the quantity of azide is very small, appropriate care should be taken when handling this material as indicated above. The National Institute of Occupational Safety and Health has issued a bulletin citing the potential explosion hazard due to the reaction of sodium azide with copper, lead, brass, or solder in the plumbing systems. Sodium azide forms hydrazoic acid in acidic conditions and should be discarded in a large volume of running water to avoid deposits forming in metal drainage pipes.
