Beschreibung: H2A.X is a 14 kD basal histone and a member of the H2 histone family. This nuclear protein is synthesized in the G1 and S phase of the cell cycle and is known to be important for recombination between immunoglobulin switch regions. H2A.X becomes phosphorylated on serine 139 after double-stranded DNA breaks. Phosphorylated H2A.X promotes DNA repair and maintains genomic stability. The 2F3 monoclonal antibody reacts with phosphorylated human H2A.X (Ser139) and has been shown to be useful for Western blotting and immunofluorescence. Distribution: Nuclear Function: Phosphorylated H2AX promotes DNA repair and maintains genomic stability. Important for recombination between immunoglobulin switch regions Modifications: Phosphorylation on Ser139 after double-stranded DNA breaks Synonyms: H2A.x, H2a/x, Histone 2A, Histone 2A.X Regulation: Synthesized in G1 and S-phase of cell cycle Structure: Basal histone, H2 histone family, 14 kD

Anwendungen

Applikationshinweise: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is 20 µl per million cells. It is recommended that the reagent be titrated for optimal performance for each application.

Reinigung: The antibody was purified by affinity chromatography, and conjugated with FITC under optimal conditions. The solution is free of unconjugated FITC.

Buffer: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and 0.2% (w/v) BSA (origin USA).

Lagerung: The antibody solution should be stored undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Beschränkungen: Nur für Forschungszwecke einsetzbar
