Comparison of extraction efficiencies with five cfDNA extraction kits when spiking cfDNA into Matrix I (HD817) or Matrix II (HD917)
Results demonstrate that Matrix II (HD917) has a higher compatibility with the most common extraction kits available for cfDNA, including bead and column based methods.
