Data / Performance

PHASIFY™ MAX cfDNA extraction kit, powered by novel PHASIFY™ technology, demonstrated 3-fold greater yields of circulating cell-free DNA (cfDNA) and circulating cell-free tumor DNA (ctDNA) in cancer patient plasma compared to the Qiagen QIAamp Circulating Nucleic Acid kit.

I. Improved yield of total DNA (cfDNA)

Figure 1 - The cfDNA was extracted from 89 tissue positive cancer patient plasma samples (1mL) using PHASIFY™ MAX and the QIAamp CNA kit. Total DNA recovery was measured using Quant-iT™ PicoGreen™ dsDNA Assay Kit. On average PHASIFY™ MAX demonstrated a 3.8-fold increase in total DNA recovery compared to QIAamp CNA (P-Value <0.0001 Wilcoxon Signed-Rank). Note, 2 outliers were excluded in which PHASIFY™ MAX generated 209x and 800x greater recovery.

II. Improved mutation detection and clinical sensitivity

Appendiceal 0.35% ND
Ovarian 2.80% ND
Ovarian 0.44% ND
Colorectal 2.10% ND

Colorectal 0.25% ND
Colorectal 0.50% ND

Colorectal 0.58% ND

ND = Not Detected, MAF = Mutant allele frequency

Figure 2 - In 13 samples, mutations were detected in samples extracted with PHASIFY™ MAX, but not with QIAamp CNA.

III. Greater recovery of desired cfDNA fragments

Figure 3 - DNA was extracted from 1 mL healthy human plasma using PHASIFY™ MAX or the QIAamp Circulating Nucleic Acid kit. The extracted DNA were analyzed on Agilent Bioanalyzer 2100, where 35bp and 10,380bp peaks correspond to internal markers.
