Biomarker Discovery in Blood and Urine

  • Blood & Urine Collection and Preservation
  • Circulating cell-free DNA Isolation
  • Circulating cell-free RNA Isolation
  • Exosome Isolation
  • Exosomal RNA Isolation

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) can provide critical information on diseases that are normally difficult to detect with standard approaches - including cancer - the interest in liquid biopsy methods for biomarker discovery and disease research is on the rise. In addition to cfDNA, 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. Purification is based on spin column chromatography that uses Norgen’s proprietary Silicon Carbide resin separation matrix. Selected products are included in our current promotion, see below.
