Principle of the Assay: H2AFX ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-H2AFX antibody and an H2AFX-HRP conjugate. The assay sample and buffer are incubated together with H2AFX-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the H2AFX concentration since H2AFX from samples and H2AFX-HRP conjugate compete for the anti-H2AFX antibody binding site. Since the number of sites is limited, as more sites are occupied by H2AFX from the sample, fewer sites are left to bind H2AFX-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The H2AFX concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
Encodes HTA3, a histone H2A protein. H2AX is a meiosis-specific isoform of histone H2A. Upon DSB formation, rapid accumulation of phosphorylated H2AX (gamma-H2AX) occurs around the break site. #H2AX foci accumulate in early G2. Immunolocalization studies in spread preparations of wild-type meiocytes at G2/early leptotene revealed the accumulation of numerous rather diffuse gamma-H2AX foci throughout the chromatin. However, their accumulation is not contemporaneous with that of AtSPO11-1. At 3 h post-S, no gamma-H2AX foci are detected. During the 3- to 5-h window when AtSPO11-1 foci rapidly disappear, there is an equally swift accumulation of gamma-H2AX to a maximum of >50 diffuse foci. The level of gammaH2AX then remains constant for a further 13 h before undergoing a gradual decrease to 10#Aei20 foci in the 18- to 24-h post-S period. By 30 h the foci have disappeared from the chromatin.
Uniprot Description
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 ().

Product Notes
The Human gamma-H2AX at1g54690 (Catalog #AAA7254195) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA7254195 ELISA Kit recognizes Human gamma-H2AX. It is sometimes possible for the material contained within the vial of "gamma H2A Histone Family, Member X, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
