Product Information

Tested Applications DB, WB

Applications Validated by Active Motif: WB*: 0.5 - 2 ug/ml DB: 0.5 - 1 ug/ml *Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western Blot. For optimal results, primary antibody incubations should be performed at room temperature. The addition of 0.1% Tween 20 to all blocking solutions may also reduce background. Individual optimization may be required. AbFlex recombinant antibodies are genetically derived from DNA sequences of parental hybridoma clones. For details on the parental clone, see Catalog No. 39529.

Background Information

AbFlex antibodies are recombinant antibodies (rAbs) that have been generated using defined DNA sequences to produce highly specific, reproducible antibodies. Each AbFlex antibody contains a 6xHis Tag, a Biotinylation Tag for enzymatic biotin conjugation using the biotin ligase, BirA, and a sortase recognition motif (LPXTG) to attach a variety of labels directly to the antibody including fluorophores, enzymatic substrates (HRP, AP), peptides, drugs as well as solid supports. ATM – Ataxia Telangiectasia Mutated is a PI3-family protein kinase and a critical cell cycle checkpoint protein. ATM and a related protein, ATR, play crucial roles in the maintenance of genome integrity and the response to DNA damage. Upon activation, ATM phosphorylates itself at serine 1981 and then phosphorylates a number of downstream proteins (e.g. BRCA1, CHK2, H2AX, p53, NBS1, SMC1) resulting in cell cycle arrest and the initiation of DNA damage repair. Loss of function of ATM is causal to a variety of syndromes involving increased incidence of several cancers.
