Estrone-2,3,4-13C3, 100 ug/mL,
|
E-108
|
100 µg/mL in Methanol
A stable-labeled internal standard of estrone, a precursor of estradiol, suitable for quantitation of estrone in serum or plasma by LC-MS/MS for clinical testing applications such as diagnosing developmental abnormalities, assessing enzyme inactivity or deficiency, or monitoring hormone replacement therapy in women. For these analyses, 13C-labeled internal standards can eliminate potential issues of isotopic exchange and minimize separation of later-eluting analytes from a higher substituted deuterium-labeled internal standard.
