  • 描述
    兔多克隆抗体to Chk2 (phospho T68)
  • 宿主
  • 特异性
    ab3501 was tested using MCF7 cells treated with different amounts of doxorubicin (a DNA damaging agent). As the treatment increased the WB signal at 60kDa representing Chk2 increased, indicating that ab3501 was detecting the phosphorylated form of the protein. It has also been shown by peptide ELISA to be specific for the phosphorylated form of the immunizing peptide versus the non-phosphorylated form.

应用 Ab评论 说明
WB 1/200 - 1/2000. Detects a band of approximately 61 kDa (predicted molecular weight: 61 kDa).


  • 功能
    Regulates cell cycle checkpoints and apoptosis in response to DNA damage, particularly to DNA double-strand breaks. Inhibits CDC25C phosphatase by phosphorylation on 'Ser-216', preventing the entry into mitosis. May also play a role in meiosis. Regulates the TP53 tumor suppressor through phosphorylation at 'Thr-18' and 'Ser-20'.
  • 组织特异性
    High expression is found in testis, spleen, colon and peripheral blood leukocytes. Low expression is found in other tissues.
  • 疾病相关
    Defects in CHEK2 are associated with Li-Fraumeni syndrome 2 (LFS2) [MIM:609265]; a highly penetrant familial cancer phenotype usually associated with inherited mutations in p53/TP53.
    Defects in CHEK2 may be a cause of susceptibility to prostate cancer (PC) [MIM:176807]. It is a malignancy originating in tissues of the prostate. Most prostate cancers are adenocarcinomas that develop in the acini of the prostatic ducts. Other rare histopathologic types of prostate cancer that occur in approximately 5% of patients include small cell carcinoma, mucinous carcinoma, prostatic ductal carcinoma, transitional cell carcinoma, squamous cell carcinoma, basal cell carcinoma, adenoid cystic carcinoma (basaloid), signet-ring cell carcinoma and neuroendocrine carcinoma.
    Defects in CHEK2 are found in some patients with osteogenic sarcoma (OSRC) [MIM:259500].

  • The Western blot shows lysates from MCF-7 cells treated for 24 hours with increasing concentrations of the DNA damaging agent Doxorubicin (0-10µM). The blot clearly shows that Chk2 phosphorylation is increased with the higher concentrations of Doxorubicin.

Thank you very much for your interest in our antibodies against Chk2 phospho Thr68.
To our knowledge, all these three antibodies have not been tested in rodent species. All these three antibodies are however predicted to react against the mouse an...

Thank you for your enquiry. We have not received any feedback from customers who have tried this antibody for cross-reactivity with mouse. Although it is predicted to cross-react due to 90% sequence homology, we cannot guarantee it. Should you decid...
