||Recombinant human full-length CHK2 were co-expressed by baculovirus inSf9insect cells using an N-terminal GST tag on both proteins. MW=88 kDa.
||CHK2 is rapidly phosphorylated and activated in response to replication blocks and DNA damage; the response to DNA damage occurs in an ataxia telangiectasia mutated (ATM)-dependent manner. Expression of wild-type Chk2 leads to increased p53 stabilization after DNA damage, whereas expression of a dominant-negative Chk2 mutant abrogated both phosphorylation of p53 on Ser-20 and p53 stabilization.
||Sf9 insect cells using baculovirus.
||Kinase Assay, Western Blot.
|Storage And Stability:
||Store product at –70°C. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
