Product Specific Information

The antibody was affinity-purified from rabbit antiserum by affinity chromatography using an epitope-specific immunogen. The purity is greater than 95% as determined by SDS-PAGE.

Target Information

Steroid 5alpha-Reductase is an important enzyme in androgen physiology, catalyzing the conversion of testosterone into the more potent 5alpha-dihydrotestosterone (DHT), which mediates androgen effects on target tissues.
There are two isoforms:

• Type 1: Expressed mainly in the skin
• Type 2: Expressed mainly in the prostate

In cultured human skin cells, 5alpha-Reductase 1 shows protein heterogeneity and variable transcriptional and translational expression levels.
It is expressed in all portions of the hair follicle, whereas 5alpha-Reductase 2 is expressed only in mesenchymal portions.
5alpha-Reductase 1 is also expressed in human breast carcinoma and may play a role in local androgen metabolism, including inhibition of cancer cell proliferation in hormone-dependent breast carcinoma.
The 5alpha-Reductase–3alpha-hydroxysteroid dehydrogenase complex is present in the human brain, suggesting involvement in the synthesis of neuroactive steroids or catabolism of neurotoxic steroids.
