* I guess that the concentration of cfDNA from Rigo is by Nanodrop. Those numbers seemed to be over-estimated since the total amount by Qubit is much lower than that I got from Illumina.

Additional cfDNA from Illumina (Nautica cfDNA)

  • Dr. Zhang received 3 additional cfDNA from Illumina
  • Sample info. from Rigo
Sample Conc. (ng/ul) Volume (ul) Amount (ng)
NORM1-02 P1 5.25 15.00 78.70
NORM1-03 P1 3.25 15.00 48.70
COLO2-03 3.05 15.00 45.80
  • I am not sure how they measure DNA concentration. I will repeat measuring concentration again.
  • To avoid losing too much DNA for re-quantification, I will add more ~7ul of EB buffer to bring the volume to 21ul and use 1ul for Qubit dsDNA quantification.

Re-quantification of cfDNA by Qubit dsDNA HS assay

Sample Conc. By Qubit (ng/ul) Amount in 20ul (ng)
NORM1-02 P1 1.66 33.20
NORM1-03 P1 0.77 15.30
COLO2-03 1.11 22.20
  • I guess that the concentration of cfDNA from Rigo is by Nanodrop. Those numbers seemed to be over-estimated since the total amount by Qubit is much lower than that I got from Illumina.
