Webinar: Improving Laboratory Workflow for Vitamin D Analysis

09 June 2015

Watch online: The Derivatization and Extraction of 25-Hydroxy Vitamin D2 and D3 in Serum Using Supported Liquid Extraction Towards Clinical Method Validation


This webinar discusses a robust sample preparation strategy and subsequent derivatizing protocol for both 25 Hydroxy Vitamin D2 and D3 in serum. The process is simple and efficient utilizing ISOLUTE® SLE+ in a 96 well plate format for high throughput processing of samples. Clinical method validation data derived via this process will also be discussed.

We explain the benefits Biotage ISOLUTE® SLE+ can bring to the lab workflow compared to traditional strategies, when processing serum for clinical method development and validation using Liquid Chromatography-Mass Spectrometry.
