抗原表位
- pSer139
-
特异性
- This antibody detects endogenous levels of Histone H2A.X only when phosphorylated at Serine 139.
-
纯化方法
- Affinity Chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatogramphy using non-phosphopeptide corresponding to the phosphorylation site.
-
免疫原
- The antiserum was produced against synthesized phosphopeptide derived from human Histone H2A.X around the phosphorylation site of serine 139 (Q-A-SP-Q-E).

背景
- Histone H2A.X is a member of the histone H2A family, 1 of 5 families of histone proteins involved in nucleosomal organization of chromatin. Histone 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 Histone H2A.X promotes DNA repair and maintains genomic stability.Synonyms: H2AFX, H2AX, H2a/x
