Nitrogen Evaporation Technique in Metabolic Extraction: European Molecular Biology Laboratory

EMBL metabolite extraction with small test tube evaporator

Small molecule chemicals found within a biological sample, known as a metabolome, can change rapidly. According to the European Molecular Biology Laboratory (EMBL), sample preparation is one of the most critical parts of a successful metabolomics experiment.  

Researches across the globe are using Organomation instruments in their metabolomics research.

EMBL, Europe’s flagship laboratory for basic research in molecular biology, demonstrates a general protocol of extraction of polar metabolites from a HeLa cell culture.

The drying step utilizes Organomation’s 24 position MICROVAP small vial evaporator in this video tutorial:

This general protocol can be adapted for other samples considering the following: type of biological matrix, sample collection, quenching of cellular metabolism, extraction and recovery of metabolites, drying, storage, and shipment.
