      DescriptionFlowCellect™ Multi-Color DNA Damage Response Kit
      OverviewMillipore’s FlowCellect™ Multi-Color DNA Damage Response Kit is designed to enable a researcher a quick and easy way to detect the phosphorylation state of ATM, SMC1 and Histone H2A.X by flow cytometry. Millipore’s FlowCellect™ Multi-Color DNA Damage Response Kit was developed and tested using the DNA damaging reagent, Etoposide, in HeLa cells as a model system but the kit can be used with other human cell lines to determine the effect of mechanical and chemical reagents that can induce DNA damage through the ATM dependent pathway.
      Millipore’s FlowCellect™ Multi-Color DNA Damage Response Kit contains sufficient reagents for 25 3-color samples. The kit includes three optimized fluorescently labeled antibodies and buffers necessary for cell preparation and analysis. Detailed assay instructions are included to assist in your analysis and to ensure that the correct cell concentration is obtained during acquisition of sample data.

      Background InformationThe signaling pathways by which cells respond to DNA damage is an important area of study for cancer research. The mammalian cell response to DNA damage is made up of highly coordinated signaling pathways that can initiate cell cycle arrest and repair or initiate apoptosis, depending on the extent and type of the damage. Cells that are defective in DNA damage signaling pathways can cause cancer because they lack the ability to sense and repair the damage, leading to genetic instability and ultimately uncontrolled cell growth.

      The main kinase activated in response to double-stranded DNA breaks is ATM or Ataxia-telangiectasia mutated kinase. ATM is a member of the phospho inositide 3-kinase (PI3K)-related Ser/Thr protein kinase family. Inactive ATM exists as a dimer but quickly dissociates and becomes phosphorylated on Serine 1981 in response to ionizing radiation.

      Once activated, ATM phosphorylates a number of downstream factors, including P53, CHK2, SMC1, NBS1 and Histone H2A.X. SMC1 is a member of the structural maintenance of chromosome family originally identified in yeast to be important for proper segregation of the chromosomes during mitosis. However, in mammalian cells exposed to IR, phosphorylation of SMC1 on sites S957 and S966 by ATM has been shown to be required for activation of the S-phase checkpoint and is important for protection against radiation induced cell death.

      Phosphorylation of the histone variant, H2A.X, at serine 139 by ATM is an important indicator of DNA damage. As the level of DNA damage increases, the level of phospho Histone H2A.X increases and accumulates at the sites of DNA damage and is often used to indicate the level of DNA damage present within the cell (8). H2AX is also responsible for recruiting response proteins to the site of DNA damage.
