CYP19 Antibody (E-9) is a mouse monoclonal IgG2a kappa light chain antibody raised against amino acids 204–503 located at the C-terminus of human CYP19. CYP19, also known as aromatase, estrogen synthase, or cytochrome P450 family 19 subfamily A member 1, is a crucial enzyme that catalyzes the conversion of androgens to estrogens. Specifically, CYP19 transforms testosterone into estradiol and androstenedione into estrone, playing a pivotal role in steroidogenesis. This enzymatic function is essential for sexual development and reproductive processes, influencing estrogen levels in various tissues such as the placenta, gonads, adipose tissue, skin, and brain. Abnormal expression or activity of CYP19 has been associated with conditions like breast cancer, familial gynecomastia, and other estrogen-dependent disorders, highlighting its significance in medical research and potential therapeutic interventions. anti-CYP19 antibody (E-9) specifically detects human CYP19 in applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). Available in both non-conjugated and multiple conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and various Alexa Fluor® conjugates, CYP19 (E-9) antibody serves as a versatile tool for studying CYP19 expression and function across diverse biological contexts.

Rated 2 out of 5 by from unsure about this antibodyHonestly, I'm not sure what to think about this antibody. I tried it a number of different tissues (human, cow, and mouse), and am not sure I can detect the correct band. I do, however, get a very bright signal at the wrong molecular weight (~30kDa) that I'm unsure of the identify of.

Rated 5 out of 5 by from Works great with porcine samples!I received a sample of this antibody for use in western blotting. It works great with porcine testis samples! It gave one beautiful band of an appropriate molecular weight. It also demonstrated linearity with increasing protein concentrations and the negative control was clear. We are very happy.
