Background Information
Histone H2A.X belongs to the histone H2A family, which is synthesized in G1 and S phase. It is involved in nucleosomal organization of chromatin together with other histone proteins, and is specially important for recombination between immunoglobulin switch regions. H2A.X becomes phosphorylated on serine 139 (to form gamma-H2AFX or H2AX139ph) in response to DNA double strand breaks (DSBs) generated by exogenous genotoxic agents and by stalled replication forks, which promotes DNA repair and maintains genomic stability. The calculated molecular weight of H2AX is 15 kDa, but the ubiquitinated H2A.X is about 22 kDa.

Reviews
What customers say
All three reviews are for Western Blot applications and rate the antibody 4–5 stars. Users report strong, specific signal at the expected ~15 kDa across mouse liver lysates, HEK293FT cells, and liver cell lines. Recommended dilutions range from 1:1000 to 1:3000 in TBST-based buffers. One user noted that adding benzonase to the lysis buffer helps recover chromatin-bound material, improving signal. Overall, reviewers describe reliable performance with good band quality and no mention of background or cross-reactivity issues.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Kamal (Verified Customer) (02-27-2025) | Mouse liver lysates were subjected to SDS-PAGE and immunoblotted with Histone H2A.X Polyclonal antibody (1:2000 in 1XTBST). Bands appeared at 15 kDa.
 |
Andreas (Verified Customer) (03-23-2022) | Antibody gives very good signal, hence the dilution factor. One important note is that I include 1:2000 dilution of benzonase in my lysis buffer to recover most of the chromatin-bound material, which big part of it is otherwise lost during the clarification step.

kes (Verified Customer) (01-17-2022) | used for WB (1:1000) in milk+TBST buffer and got good results
