Aurora Versa LLE workstation for vitamin D extraction

Thursday, 07 October, 2010 | Supplied by: Biospek Pty Ltd


Vitamin D deficiency is associated with many pathological conditions including diabetes, osteoarthritis and many forms of cancer.

Several methods are available to assess vitamin D sufficiency through measurement of serum 25-hydroxy vitamin D. Antibody (ELISA) or other protein-binding assays are available, but may not accurately report total vitamin D values. Moreover, manual sample preparation methods for assays such as LC-MS/MS or HPLC are very cumbersome.

Aurora’s Versa LLE workstation has been validated for the organic solvent extraction of 25(OH)D from blood serum using liquid-liquid extraction (partition chromatography). Reliable reproducibility of peak height data from the extractions suggests that biomolecules like 25(OH)D can be effectively extracted using this automation within acceptable values. Moreover, the automated process takes 60 minutes for a set of 96 samples with no detectable cross-contamination. The extraction process takes approximately 17 minutes less than the manual procedure.

25-hydroxy vitamin D extraction using the Versa LLE workstation is just one of many application solutions offered by Aurora. Numerous applications that are widely used have been automated and each Versa workstation remains customisable to accommodate unique needs.
