(tested or 100% immunogen sequence identity)
Predicted
Chimpanzee, Mouse, Rat (at least 90% immunogen sequence identity)
Conjugations
Unconjugated
Purification
Affinity purified
Immunogen
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal region near aa 50-75 of Human CHK2.
Specificity
Reactivity occurs against human CHK2 pT68 protein and the antibody is specific for the phosphorylated form of the protein. Reactivity with non-phosphorylated human CHK2 is minimal by ELISA. The antibody does not cross-react with Chk2 phosphorylated at other sites. A BLAST analysis was used to suggest reactivity with this protein from human and chimpanzee based on 100% homology for the immunogen sequence. Cross reactivity with CHK2 protein from mouse and rat may occur as sequence homology varies by one amino acid residues in this sequence (90% homology). Cross reactivity with CHK2 homologues from other sources has not been determined.
Applications
- Western blot (1:200 - 1:2000)
- Immunoprecipitation (1:100)
- ELISA (1:10000 - 1:70000)
Usage
This affinity purified antibody has been tested for use in ELISA and by western blot. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 61 kD in size corresponding to CHK2 by western blotting in the appropriate cell lysate or extract. Less than 1 % reactivity is observed against the non-phosphorylated form of the immunizing peptide. This antibody is phospho specific for pT68 of CHK2.
