Product Overview
This rabbit polyclonal antibody targets histone H3.3 (gene h3f3a) in zebrafish samples and is validated for Western blot, IHC and ICC/IF.
In zebrafish, histone H3.3 (h3f3a) is a replacement H3 variant that is deposited into chromatin independently of DNA replication, mainly at actively transcribed regions. It helps mark active chromatin and is the dominant H3 form in non-dividing cells. Zebrafish H3.3 is studied in chromatin dynamics, development and neural crest biology.

Samples with a confirmed band (WB): zebrafish head tissue, whole female zebrafish tissue, whole male zebrafish tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Samples with confirmed staining (ICC/IF): zebrafish embryo tissue.
Samples with confirmed staining (IHC): zebrafish brain tissue, zebrafish liver tissue, zebrafish colon tissue, zebrafish muscle tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Immunogen
E. coli-derived zebrafish.
Reactivity Notes
The supplier lists reactivity with zebrafish. UniProt places histone H3.3 in the nucleus and chromosome. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
