a cfDNA extraction kit using silica column method

IDXtract is an extraction kit of circulating cell-free DNA (cfDNA) optimized for use on biological samples such as blood plasma.

The kit is based on silica membrane columns, that allows reproducible recovery of high-quality cfDNA.

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