Oxysterols are produced through enzymatic or non-enzymatic oxidation of cholesterol.{60076} They function as metabolic intermediates or bioactive lipids and are involved in the regulation of cholesterol and lipid metabolism and have roles in cell signaling and innate and adaptive immunity, among others. For example, 24(S)-hydroxy cholesterol is important for sterol homeostasis in the CNS, several oxysterols act as liver X receptor (LXR) ligands, and 25-hydroxy cholesterol regulates cholesterol biosynthesis. 25-hydroxy Cholesterol also inhibits replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro and increased rapidly prior to death in the serum of a patient with COVID-19, the primarily respiratory virus caused by SARS-CoV-2.{60053} Cayman’s Oxysterol Derivatization MaxSpec® Kit is designed for the sensitive detection and relative quantitation of oxysterols in biological samples. This is achieved through enzyme-assisted derivatization utilizing d0/d5 labeled Girard’s P (GP) reagent to give GP hydrazones. The instrumental response of the derivatized oxysterols is significantly improved due to the presence of a positively charged quaternary nitrogen group in the labeled and unlabeled GP hydrazones. Included in this kit are the essential reagents to derivatize oxysterols in mixtures for sensitive and comparative LC-MS analysis.

Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
