Product Overview
This rabbit polyclonal antibody targets aromatase (gene CYP19A1) in human, mouse and rat samples and is validated for ELISA, flow cytometry, IHC, ICC/IF and Western blot. The predicted molecular weight is 57.9 kDa, and the supplier reports an observed band at about 58 kDa.
Aromatase (CYP19A1) is the cytochrome P450 enzyme that converts androgens into estrogens, turning androstenedione into estrone and testosterone into estradiol. It is expressed in the ovary, placenta, adipose tissue, bone and brain, and it is the target of aromatase inhibitors used in breast cancer, so it is central to studies of estrogen biology and hormone-dependent cancers.

Samples with a confirmed band (WB): human placenta tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Samples with confirmed staining (IHC): human placenta tissue, mouse small intestine tissue, rat lung tissue, rat small intestine tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in citrate buffer (pH 6).
Samples with a confirmed signal (flow cytometry): U2OS cells.
Immunogen
Recombinant human CYP19A1 fragment (Tyr241–His503), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places aromatase in the endoplasmic reticulum membrane and microsome membrane. Tissue expression noted by UniProt (human): Widely expressed, including in adult and fetal brain, placenta, skin fibroblasts, adipose tissue and gonads. 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).
