17beta-Estradiol-2,3,4-13C3,
|
E-117-1ML
|
10 ug/mL in Acetonitrile
Estradiol is a sex hormone prescribed under the trade names Vagifem, Estring, Evamist, Elestrin, Estrace, and Estrogel as a treatment for hypoestrogenism. Estradiol is measured in women to assess activity of the ovaries and overall reproductive function. This 13C-labeled internal standard is suitable for quantitation of estradiol levels in women, men, or children by LC/MS in applications for endocrinology, female health testing or clinical chemistry.

Estrone-2,3,4-13C3, 10 ug/mL,
|
E-118-1ML
|
10 ug/mL in Methanol
Estrone, a precursor of estradiol, is monitored in serum or plasma by LC-MS/MS or GC/MS to assess and diagnose developmental abnormalities, enzyme inactivity or deficiency, polycystic ovary syndrome (PCOS), or hormone replacement therapy in women. This 13C-labeled internal standard of estrone is suitable for quantitation of estrone in serum or plasma by LC-MS/MS or GC/MS for clinical testing and can eliminate potential issues of isotopic exchange as well as minimize separation of later-eluting analytes from a higher substituted deuterium-labeled internal standard.
