Oxysterols are intermediates in the biosynthesis of both bile acids and steroids, but some may also have their own biological activities in vivo. Conditions such as Alzheimer’s Disease, Multiple Sclerosis, and various cancers may be connected to altered oxysterol levels as well. OxysterolSPLASH TM contains 13 deuterated oxysterols at equal concentrations, making the mixture a useful tool for lipidomic analysis of these compounds.
The original SPLASH TM internal standard mixture has been a best-seller since it was first developed in 2016. It contains one deuterium labeled internal standard for each of 14 lipid classes at ratios relative to human plasma lipids. Each vial contains 1mL of internal standard mixture in methanol solution with a suggested sample spiking ratio of 10μL SPLASH TM to 10μL human plasma, allowing for up to 100 samples to be analyzed with one vial. Concentrations are verified for use as a quantitative standard.
