| Product Name | 3α-hydroxysteroid dehydrogenase enzyme raw material for diagnostic kits, specific activity >=30 U/mg, CAS 9028-56-2 |
| Catalog No. | IEC-HMM-0138 |
| Description | 3α-hydroxysteroid dehydrogenase (3α-HSD, CAS 9028-56-2) is a high-quality enzyme raw material intended for the manufacture of in vitro diagnostic reagent kits. The product is supplied as a white to slightly yellow amorphous powder with a specific activity of no less than 30 U/mg and an approximate molecular weight of 40 kDa. It exhibits an isoelectric point of 5.3 and is not inhibited by sodium azide, allowing flexible formulation of reagent systems. The enzyme remains stable across a broad pH range of 6.0 to 10.0, with an optimal pH of 10, and shows an optimal reaction temperature of 55°C with thermal stability up to 50°C. When stored at -20°C, the enzyme retains its activity for at least one year, making it a reliable and robust component for diagnostic kit development and production. |
