The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

For antigen retrieval, heat up to 98 °C, below boiling, and then let cool for 10-20 minutes.

ICC/IF Use at an assay dependent concentration.
  • Application notes
    Is unsuitable for WB.
  • Target

    • Function

      Component of the post-replicative DNA mismatch repair system (MMR). Heterodimerizes with MSH2 to form MutS beta which binds to DNA mismatches thereby initiating DNA repair. When bound, the MutS beta heterodimer bends the DNA helix and shields approximately 20 base pairs. MutS beta recognizes large insertion-deletion loops (IDL) up to 13 nucleotides long. After mismatch binding, forms a ternary complex with the MutL alpha heterodimer, which is thought to be responsible for directing the downstream MMR events, including strand discrimination, excision, and resynthesis.
    • Involvement in disease

      Defects in MSH3 are a cause of susceptibility to endometrial cancer (ENDMC) [MIM:608089].
    • Sequence similarities

      Belongs to the DNA mismatch repair mutS family. MSH3 subfamily.
    • Post-translational

      Phosphorylated upon DNA damage, probably by ATM or ATR.
