General description

Histone H2A is one of the 5 main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N terminal tail H2A is involved with the structure of the nucleosomes of the ′beads on a string′ structure.

Specificity

Broad species cross-reactivity expected based on conservation of sequence homology.
Histone H2A.X phosphorylated at Ser139.

Immunogen

Epitope: a.a. 134-142

Application

Anti-phospho-H2A.X (Ser139) Antibody is a Rabbit Polyclonal Antibody for detection of phospho-H2A.X (Ser139) also known as histone 2 H2ac, histone IIa & has been validated in IP & WB.
Immunoprecipitation:
A previous lot of this antibody successfully immunoprecipitated phosphorylated H2A.X as determined by an independent laboratory.

Quality

Routinely evaluated by Western Blot on untreated and staurosporine treated Jurkat lysate.

Western Blot Analysis:
1:500 dilution of this lot detected phospho-H2A.X on 10 μg of staurosporine treated Jurkat lysate.

Target description

15 kDa

Linkage

Replaces: MABE205

Physical form

Format: Purified

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C.
Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol-containing solutions to become frozen during storage.
