Qiagen PAXgene Blood CcfDNA Tube

Qiagen has launched its PAXgene Blood ccfDNA tube for venous whole blood collection and room temperature stabilization of in-vivo circulating cell-free DNA profiles. The new system contains a non-crosslinking reagent in the collection tube that ensures DNA remains unmodified. It prevent post-collection release of genomic DNA from white blood cell — resulting in improved ccfDNA yield recovery with less background DNA, the company said.
