Liquid Biopsy - Biomarker Discovery in Blood and Urine

Isolate high-quality, inhibitor-free DNA and RNA of all sizes from plasma/serum and urine samples.

Liquid biopsy is a method to obtain biomarkers directly from body fluids such as blood or urine instead of solid tissue. It is a simple and non-invasive alternative to surgical biopsies. With the growing recognition that circulating cell-free DNA (cfDNA) and RNA (cfRNA) can provide critical information on diseases that are normally difficult to detect with standard approaches, the interest in liquid biopsy methods for biomarker discovery and disease research is on the rise. In addition to circulating cell-free nucleic acids, exosomes are also a rich source of biomarkers that are amenable to the straightforward liquid biopsy approach.

To facilitate biomarker discovery in liquid biopsies, BioCat offers comprehensive tools for the complete workflow from the collection and preservation of blood or urine through the enrichment and purification of cfDNA, cfRNA and exosomal RNA as well as DNA and total RNA/microRNA. Selected products developed by our partner Norgen Biotek for the isolation of high-quality, inhibitor-free DNA and RNA of all sizes from plasma/serum or urine samples are included in our current promotion, see below.
