{"product_id":"f54477-0-2ml","title":"Histone H2AX Antibody \/ H2AFX","description":"\u003cp\u003eVariant 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.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.2 ml \/ Mouse","offer_id":49477117182232,"sku":"F54477-0.2ML","price":429.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_b0b057c4-91cf-404c-b7ed-00b0d3e66c7d.jpg?v=1734490939","url":"https:\/\/danabiosci.com\/products\/f54477-0-2ml","provider":"Dana Bioscience","version":"1.0","type":"link"}
