Quantification of DNA or RNA


Quantification of nucleic acids can be achieved via UV spectroscopy or via the use of fluorometry (in combination with DNA (PicoGreen) or RNA (RiboGreen)-binding dyes).

The NanoDrop instrument for UV quantification consumes only 1-2 ul of material, and provides a measure of DNA purity (260/280 and 260/230 ratios), but is not able to accurately quantify impure nucleic acids or DNA or RNA at concentrations below ≈ 10 ng/ul.

PicoGreen and RiboGreen quantification are therefore the gold standards for sensitive and specific quantification of DNA and RNA, respectively.


Please contact our QC team at umgc-qc@umn.edu for more information and questions regarding quantification.

Print and submit the completed submission form with your samples.

Please submit 4 ul of sample per assay in a 96-well plate (fill plate starting with A1-H1, A2-H2, etc.). Example: if requesting both NanoDrop and PicoGreen, please submit 8 ul of sample.

For NanoDrop submissions, please also provide 2 ul/sample blanking solution if other than water.

Samples can be dropped off at one of our laboratory locations.

For RNA samples, please make sure samples are submitted directly to a UMGC staff member so that the samples are stored appropriately. DNA samples can be placed in the indicated freezer.

  • 1-210 Cancer & Cardiovascular Research Building (Minneapolis campus) small freezer in the lobby.
  • 28 Snyder Hall (St. Paul campus) – please drop off directly with UMGC staff. We have a fridge, not a freezer in Snyder 20.


An Excel report is emailed to client with sample IDs and concentrations.


What is the turnaround time?

The UMGC guarantees a turnaround time of 3 days. Often results are sent out within 24 hours of sample submission.
