This finding can be viewed in a recent publication in the International Journal of Medical Sciences which highlights the key benefits of Norgen's cf-DNA/cf-RNA Preservation Tubes for the analysis of circulating nucleic acids in liquid biopsies (

Scientists at the University Hospital of Heidelberg and the German Cancer Center carried out studies to test the limits of conventional EDTA tubes as well as long-term storage blood collection tubes (BCTs) from four different manufacturers for their potential applications in clinical diagnostics, including Norgen's cf-DNA/cf-RNA Preservative Tubes, Streck's Cell-Free DNA Tubes, Roche Diagnostic's Cell-Free DNA Collection Tube and PreAnalytiX's PAXgene Blood ccfDNA Tubes. Their findings were recently published in the paper "Evaluation of Storage Tubes for Combined Analysis of Circulating Nucleic Acids in Liquid Biopsies", and the following conclusions were made: First, they found that Norgen's tube is one of the best at stabilizing cf-miRNAs, and thus the most suitable for...

"I am delighted that these scientists concluded what had already been found by our scientists – Norgen's BCT tubes outperform the competition. It is our commitment to quality and novelty that enabled us to develop this Best-In-Class and First-In-Class product. This is the only product that preserves for 30 days, and gets you both the cf-DNA and cf-RNA from the same tube, so that one can study both genomics and transcriptomics. Furthermore, Norgen's cf-DNA/cf-RNA BCT tubes are very suitable for ct-DNA studies.  Norgen is proud to offer the scientific community a full solution for liquid biopsies from preservation to isolation manually or using automation" said Dr. Yousef Haj-Ahmad, President & CEO of Norgen Biotek.
