DNA-Depleted Plasma (cfDNA reference material)

 

cfDNA reference material

Build your own controls using your high-positive samples to save time. With our DNA-depleted human plasma (DNA-free plasma) as a matrix, you can produce reference materials specific to your time-sensitive needs while retaining the natural components of the sample.

Why Is Plasma Better Than Buffer As Reference Material Matrix?

A plasma matrix is a better representation of a real patient sample because the natural, interfering proteins are retained. This allows for a more realistic process in your quality system.

Equal amounts of DNA fragments were spiked into TE Buffer (blue) and human plasma (red).

While the 170 bp peak was recovered similarly in each matrix, much more genomic DNA was extracted from the plasma than from the TE buffer resulting in a more patient-like matrix.
See Figure A.

 

Exosome counts in DNA-depleted plasma are normal compared to regular plasma.
