Rabbit polyclonal antibody to Histone H2A.X (Phospho-Ser139)
Specificity
The antibody detects endogenous level of Histone H2A.X only when phosphorylated at serine 139.
Applications
WB, ICC/IF
Dilutions
Western blotting: 1:500~1:1000 Immunofluorescence: 1:100~1:200
Reactivity
Human
Immunogen
Peptide sequence around phosphorylation site of serine 139 (Q-A-S(p)-Q-E) derived from Human Histone H2A.X.
Host
Rabbit
Clonality
Polyclonal
Conjugate
Unconjugated
Purification
Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
