Description

General description

17α-Hydroxypregnenolone is a steroid hormone produced in the adrenal glands. This hormone is monitored as an ancillary test for congenital adrenal hyperplasia (CAH), particularly in situations where diagnosis of 21-hydroxylase and 11-hydroxylase eficiency has been ruled out. This Certified Spiking Solution^® is suitable for use as starting material in linearity standards, calibrators, and controls fo numerous LC-MS/MS applications in endocrinology, clinical chemistry, and neonatal screening.

Application

• Enhancement of Steroidogenic Enzyme Assays: The role of protein-protein and protein-membrane interactions in cytochrome P450 function, which is crucial for understanding the enzymatic activities involved in steroid biosynthesis, including those mediated by 17 alpha-Hydroxypregnenolone (Scott EE et al., 2016).


• Modeling Steroid Hormone Biosynthesis: Research explores how ligand and cytochrome b5 modulate the conformation of human cytochrome P450 17A1, a key enzyme in the biosynthesis of neurosteroids from precursors like 17 alpha-Hydroxypregnenolone, providing insights for biochemical steroidogenesis research (Estrada DF et al., 2014).


• Development of ELISA for Steroid Detection: The study demonstrate the covalent coupling of steroids to microwell plates, facilitating the use of 17 alpha-Hydroxypregnenolone in competitive enzyme-linked immunosorbent assays (ELISA) for steroid hormone precursor detection and quantification in biochemical assays (Yonezawa S et al., 1993).
