Nonacus understands that every clinical sample is precious and that working with cell-free DNA (cfDNA) for prenatal applications (cffDNA) or oncology applications (ctDNA) requires exquisitely sensitive and accurate measurement of genomic alterations. Owing to the relative scarcity of cfDNA we have developed range of pre-analytical products which will ensure the very best outcome for your experiment. These include our Cell3 Preserver tube, an evacuated whole blood collection tube which stabilises the nucleated cell fraction within blood and conserves the cell-free DNA fraction and our flexible and robust Cell3 Xtract, cfDNA extraction kit which maximises input volume of patient plasma and elutes in a smaller volume providing more cfDNA and at a higher concentration.
