Case study

Quantification of biomolecules with UV5Nano.

The Pharmaceutical Biosciences laboratory at the University of Oslo analyzes up to 300 samples of biomolecules every day with the aim of developing a treatment for a bacterial disease in fish. To do so the research group uses different kits to prepare DNA, RNA, and protein samples. The quantification of RNA and other biomolecules is then performed with the predefined Bio Applications in the direct measurement mode available on the UV5Nano instrument. An example of RNA measurements in adult zebra fish is included in the article.
