Description:
H2A.X Phosphorylation Assay Kit (Flow Cytometry)
Trade Name:
Upstate (Millipore)
Qty/Pk:
1 kit
Product Overview:
Phosphorylation of the histone variant H2A.X is a rapid and sensitive response to double strand DNA breaks. The H2A.X Phosphorylation Assay Kit (Flow cytometry) is a cell based assay formatted for flow cytometric detection of levels of phosphorylated histone H2A.X.
The H2A.X Phosphorylation Assay Kit (Flow cytometry) is a cell based assay formatted for flow cytometric detection of levels of phosphorylated Histone H2A.X. Cells are cultured in microplates, treated with agents that induce DNA damage or apoptosis, which stimulates H2A.X phosphorylation. Cells are then fixed and permeabilized in preparation for staining and detection. Histone H2A.X phosphorylated at serine 139 is detected by the addition of the anti-phospho-Histone H2A.X, FITC conjugate. Cells are then scanned in a flow cytometer to quantitate the number of cells staining positive for phosphorylated Histone H2A.X.

Entrez Gene Summary:
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene encodes a member of the histone H2A family, and generates two transcripts through the use of the conserved stem-loop termination motif, and the polyA addition motif.

UniProt Summary:
FUNCTION: SwissProt: P16104 # Variant histone H2A which replaces conventional H2A in a subset of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Required for checkpoint-mediated arrest of cell cycle progression in response to low doses of ionizing radiation and for efficient repair of DNA double strand breaks (DSBs) specifically when modified by C- terminal phosphorylation.
