Store at 4 °C or at -20 °C if preferred. Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.<br>Shelf Life: 18 months from date of despatch.

This item detects Saccharomyces cerevisiae Rad9, a protein involved in the DNA damage checkpoint. In S. cerevisiae this checkpoint is mainly controlled by the PI(3) kinase-like kinase (PIKK) Mec1, which is activated in response to DNA damage. Activated Mec1 hyperphosphorylates Rad9, which in turn triggers the binding of Rad53, the orthologue of mammalian Chk2. Activated Rad53 specifically targets substrates required for cell cycle arrest, gene expression and efficient DNA repair. Mutations affecting Rad9 impair checkpoint induced cell-cycle arrest and increase genomic instability. <br> <br>This antibody is pan reactive with both the phosphorylated and non-phosphorylated forms of this protein.
