IDXTRACT is an extraction kit of total circulating DNA (cfDNA) optimized for use on biological samples such as blood plasma.

The kit is based on silica membrane columns, allowing reproducible recovery of high quality cfDNA. It contains a calibrated Positive Control (TPC) and an Internal Extraction Control (ICE) allowing the qualification and the quantification of the extraction process and the standardization of the concentration for each sample.

This kit concentrates the total cfDNA in a small elution volume suitable for a wide range of applications, including real-time PCR, digital PCR (dPCR), next-generation sequencing (NGS) and genomic hybridization technologies.
