This poster compares the use of supported liquid extraction (ISOLUTE® SLE+) and a novel protein and phospholipid depletion plate (ISOLUTE® PLD+), for the extraction of 25-hydroxy vitamin D. The extraction protocols were ultimately transferred to an SPE automation platform and method performance versus manual processing compared.
Vitamin D deficiency can result in various health issues such as osteoporosis, liver and kidney problems, and is associated with increased risk of cancers and multiple sclerosis. From this standpoint vitamin D analysis has extremely important clinical relevance. Many sample preparation approaches to the extraction of 25-hydroxy vitamin D have been employed prior to LC-MS/MS analysis. Simple protein precipitation, supported liquid extraction and complex SPE methodology are all in routine use.
