Background: The functionally related ATM (ataxia telangiectasia-mutated) and ATR (ATM-Rad3-related) protein kinases are critical regulators of DNA damage responses in mammalian cells. ATM and ATR share highly overlapping substrate specificities and show a strong preference for the phosphorylation of Serine (S) or Threonine (T) residues followed by Gln. It also called SQ or TQ consensus sites.

Purification and Purity: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).

Storage and Stability: Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles.

Specificity: Phosphorylated

Bioworld Molecular Weight: 38-68KDa

Immunogen: A synthetic peptide corresponding to a sequence containing phosphorylated S &T.

Conjugate: Unconjugated

Modification: Phosphorylated

Note: For research use only, not for use in diagnostic procedure.
