Product Overview
Clone ACA-6 is a rabbit monoclonal antibody that recognizes forkhead box protein O3 (gene FOXO3) in human samples and is validated for Western blot, IHC and ICC/IF. The predicted molecular weight is 71.3 kDa, and the supplier reports an observed band at about 76–90 kDa.
FOXO3 is a forkhead transcription factor inhibited by AKT phosphorylation downstream of insulin and growth factor signaling. When active in the nucleus, it drives genes for autophagy, oxidative stress resistance, cell cycle arrest and apoptosis. FOXO3 is studied in stem cell maintenance, muscle atrophy, cancer and aging.

Samples with confirmed staining (IHC): human bladder carcinoma tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Samples with confirmed staining (ICC/IF): HeLa cells.
Immunogen
Synthetic peptide based on the sequence of human foxO3a.
Reactivity Notes
The supplier lists reactivity with human. UniProt places forkhead box protein O3 in the cytoplasm, nucleus, mitochondrion matrix and mitochondrion outer membrane. Tissue expression noted by UniProt (human): Ubiquitous. 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).
