WebH2AX is a variant of histone H2A, one of the histone core molecules forming the nucleosome, and is a vital component in repairing DNA damage (1-4). The H2AX variant represents between 2-25% of total H2A (1-3). Human H2AX protein is 143 amino acids in length and has a theoretical molecular weight of 15 kDa (5). Webb) Immunofluorescence showing H2AX Ser 139 staining in DU-145 cells treated with 1.5 mM VPA for 48 h and irradiated with 4Gy radiation followed by 4 h repair time.
