WB Use a concentration of 1 µg/ml. Detects a band of approximately 450 kDa (predicted molecular weight: 469 kDa).

An increase in signal is observed upon UV treatment


  • Relevance

    Several protein kinases mediate cellular responses to DNA damage. This includes the serine/threonine kinases ATM (ataxia telangiectasia mutated) and ATR (ATM and Rad3-related). In response to DNA damage ATM and ATR phosphorylate a large range of proteins on Serine (S) or Threonine (T) residues next to a Glutamine (Q) residue, so called SQ or TQ consensus sites.

    Exposure time: 8 minutes

    This blot was produced using a 3-8% Tris Acetate gel under the TA buffer system. The gel was run at 150V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab130947 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
