Steroids Analysis Service


A steroid is an  organic compound with four rings arranged in a specific configuration, such as  dietary lipid cholesterol, estradiol, testosterone and dexamethasone. Steroids  function as important components of cell membranes and many of them are  signaling molecules. The core  structure of the steroid is composed of seventeen carbon atoms, bonded in four  "fused" rings: three six-member cyclohexane rings and one five-member  cyclopentane ring. Hundreds of  steroids are found in plants, animals and fungi. All steroids are manufactured  in cells from the sterols lanosterol (animals and fungi) or cycloartenol  (plants). Lanosterol and cycloartenol are derived from the cyclization of the  triterpene squalene.

Steroids Analysis Service

Equipped with  advanced LC/MS/MS sophisticated detection techniques, and a panel of experienced  scientists and technicians. Steroids analysis service is able to quantification  up to 38 steroids in biological matrices such as plasma, serum, tissue, cells,  and cell culture media.

Sample preparation  and extraction of steroids is by either liquid-liquid extraction (LLE) or  supported liquid extraction (SLE) followed by an on-line 2D polishing  extraction. Target steroid analytes are chromatographically separated on a  reverse-phase (RP) column. All analytes and Internal Standards are measured by  ESI ionization--pos and/or neg polarity (analyte dependent). Creative  Proteomics provide customer-tailored service with rapid analysis procedures and  easy to read report, to speed up your scientific research.
