{"product_id":"new-product-229708","title":"Histone H2A.X (phospho-S139) polyclonal antibody","description":"\u003cp\u003eH2A.X is a member of the histone H2A family, 1 of 5 families of histone proteins involved in nucleosomal organization of chromatin. H2A.X is synthesised in G1 as well as S phase and is known to be important for recombination between immunoglobulin switch regions. A very early step in the response of mammalian cells to DNA double-strand breaks is the phosphorylation of histone H2A.X at serine 139 at the sites of DNA damage. There is a predicted acetylation at residue 1 and ubiquitination at reside 119. Phosphorylated H2A.X promotes DNA repair and maintains genomic stability.\u003c\/p\u003e","brand":"Bioworld","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse,Rat","offer_id":47662613528856,"sku":"BS5023","price":348.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/BIOWORLD_a4d91ff0-fc82-40db-9269-930597cf6a09.jpg?v=1707491104","url":"https:\/\/danabiosci.com\/products\/new-product-229708","provider":"Dana Bioscience","version":"1.0","type":"link"}
