CYP19A1 antibody targets the cytochrome P450 family 19 subfamily A member 1 (CYP19A1), also known as aromatase, a key enzyme responsible for converting androgens like testosterone into estrogens (estradiol, estrone). This enzyme plays a critical role in steroid hormone biosynthesis, influencing reproductive function, bone health, and metabolic processes. CYP19A1 is expressed in gonads, adipose tissue, brain, and placenta, with tissue-specific regulation impacting estrogen levels in both physiological and pathological contexts, such as breast cancer, endometriosis, and polycystic ovary syndrome (PCOS).
CYP19A1 antibodies are widely used in research to study aromatase expression patterns, localization, and hormonal regulation. They enable detection of the enzyme via techniques like Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF). Specific applications include investigating estrogen-dependent cancers, where aromatase inhibitors are therapeutic targets, or exploring sex hormone imbalances in metabolic disorders. Antibodies may be monoclonal or polyclonal, with validation often involving knockout (KO) models or enzymatic activity assays to confirm specificity.
When selecting CYP19A1 antibodies, researchers prioritize reactivity across species (human, mouse, rat) and compatibility with formalin-fixed paraffin-embedded (FFPE) tissues for clinical samples. Proper controls and validation are essential due to potential cross-reactivity with other cytochrome P450 enzymes. These tools remain vital for advancing studies in endocrinology, oncology, and developmental biology.
