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.

Submission
NanoDrop Quantifiation, PicoGreen RNA Quantification, and RiboGreen RNA 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.
Forms
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).
- 20 Snyder Hall (St. Paul campus) – self-serve drop-off room.
