The nRichDX cfDNA Reference Standard contains 5 single-use tubes containing 1 mL at a 1 ng/µl concentration in TE Buffer. Comparing the spike-in amount to the recovery amount, the percent recovery is determined.

The cfDNA Reference Standard contains mononuclear DNA (mnDNA) containing the KRAS G12V mutation and the TP53 Arg158Leu, which is an established standard for spike-and-recovery extraction analysis for cfDNA*.

The expected mnDNA size is 150 bp. mnDNA is obtained from the NCI-H441 lung cancer cell line. Dinucleosomes and trinucleosomes may also be observed at the given multiples of 340 bp and 560 bp.
