Cerilliant Introduces New Stable-Labeled Internal Standard for Testosterone-2,3,4-13C3

Testosterone-2,3,4-13C3, T-070
100 ug/mL in Acetonitrile

A stable-labeled internal standard for monitoring serum testosterone levels in men, women, and children by LC-MS/MS. The Centers for Disease Control (CDC) Hormone Standardization Project cites Testosterone-2,3,4-13C3 as the internal standard of choice for measurement of testosterone at low concentrations in biological fluids by LC-MS/MS. 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. Acetonitrile was chosen as diluent for its ease of handling and miscibility with water and biological specimens.

In addition to Testosterone (T-037), we offer a wide variety of hormones and steroids Certified Spiking Solutions® for clinical and diagnostic testing including native compounds, metabolites and stable labeled internal standards of cortisol, DHEA, progesterone, estradiol, testosterone, androstenedione, and vitamin D.

Cerilliant Certified Solution Standards and Certified Spiking Solutions are manufactured to the highest industry standards. We are accredited to ISO 17034 and ISO/IEC 17025 & certified ISO 9001.
