Description

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 is expected based on conservation of sequence homology.

Recognizes Histone H2A.X phosphorylated at Ser139, MW 15 kDa.

Immunogen

Epitope: Ser139

KLH-conjugated, synthetic peptide (CKATQA[pS]QEY) corresponding to amino acids 134-142 of human histone H2A.X. The immunizing sequence has 8 identical amino acids in yeast and mouse. Clone JBW301.

Application

Immunocytochemistry: 2-4 μg/mL of a previous lot detected phospho-histone H2A.X in etoposide-treated HeLa cells fixed with 95% ethanol/5% acetic acid (10 minutes), followed by 1% formaldehyde, 0.25% Triton^™ X-100 in TBS (5 min.).

Use Anti-phospho-Histone H2A.X (Ser139) Antibody, clone JBW301, FITC conjugate (mouse monoclonal antibody) validated in FC, ICC to detect phospho-Histone H2A.X (Ser139) also known as H2AXS139P, H2AX histone.

Quality

Evaluated by Flow Cytometry to detect Log phase Jurkat cells treated with staurosporine.

Flow Cytometry: Log phase Jurkat cells were treated with staurosporine (1 μg/mL) for the indicated time. Histone H2A.X (Ser 139) phosphorylation was detected as described in the manual for the H2A.X Phosphorylation Assay Kit (Flow Cytometry), Catalog # 17-344. Cells were analyzed on a Becton-Dickinson FACS-Calibur flow cytometer.
