Sterol Lipids Analysis Service

Sterols are a group of naturally occurring substances derived from hydroxylated polycyclic isopentenoids having a 1,2-cyclopentanophenthrene structure. The sterols generally can be categorized into three subclasses: 4,4-desmethylsterols, 4a-methylsterols and 4,4-dimethylsterols. Sterols are known to have a wide range of biological activities and physical properties. Sterols Lipid Analysis Service at Creative Proteomics is aimed to simplify your research steps. Our scientist devotes their work in SOP optimized and analytical equipment improvement.

Significance Of Targeted Detection Of Sterol

Steroid hormones, also known as steroid hormones, are structures composed of four fused rings, whose precursor is cholesterol. Cholesterol undergoes a series of metabolic reactions to produce five steroid hormones: progesterone, glucocorticoid, mineralocorticoid, estrogen and androgen. The increase or decrease of human steroid hormones is closely related to some common clinical diseases, such as congenital adrenal hyperplasia, Cushing's syndrome, polycystic ovary syndrome, adrenal insufficiency, etc. By monitoring the changes in the content of steroid hormones in the human body, it is very important for clinical testing And diagnosis is one of the crucial means.

Steroid hormones and their metabolites are characterized by diverse structures, generally low content, similar skeleton structures, physical and chemical properties, and stereoisomers with identical structures. These factors present significant challenges for the efficient and accurate detection of steroid hormones.

Methods Of Targeted Detection Of Sterol

Liquid chromatography tandem mass spectrometry (LC-MS/MS) technology is one of the commonly used metabolites detection and analysis methods. Due to its strong specificity, high sensitivity, and fast analysis speed, it is favored by mass spectrometry scholars and medical researchers.

In order to provide better service, Creative Proteomics has developed a high-throughput, high-coverage, high-sensitivity targeted quantification method for steroids. Through one analysis, the levels of multiple steroid hormones can be quantified at the same time, which can effectively save manpower and material resources, improve throughput and meet the detection requirements of most steroid hormones in the laboratory.
