The role of UV-Vis in quality control of biopharmaceuticals
Recently, there have been several recent developments in the field of international medical health that continue to attract the attention of the industry and the public. In this interview, industry expert Brian Matlock explains how to evaluate nucleic acid and protein concentrations using UV-Vis and fluorescent measurements. He also discusses the role of nanoparticles in supporting faster nucleic acid and protein QC.
I've worked with NanoDrop for more than 20 years, and when I think back to graduate school and the early years of my career, we're using Cuvettes and the traditional UV-Vis method almost every day to measure the concentration of DNA and RNA. There are many pain points in this process. You have to dilute, clean QuartzCuvettes between samples, and then manually calculate the concentration.
NanoDrop enables direct concentration readings of microscopic measurements, and uses variable path lengths to enable it to cope with a variety of concentrations. Thus, it simplifies this critical step in a molecular biology laboratory into a time-consuming task, with space for user-to-user measurement differences. The basic principle of UV-Vis measurement is that the process of absorbing light is directly related to the concentration of the sample when the sample absorbs light within a specific wavelength range.
One of the most useful features of NanoDrop is that it is able to efficiently collect and extract complete data from samples across the spectrum rather than just a single concentration value. This means that you can also get insights from the sample about other substances that may be present in the sample, such as protein contamination, organic compounds, or other impurities that may affect the downstream work. UV-Vis is also unlabeled technology, so you don't add anything extra to the sample.

NanoDrop provides a simple and easy way to get accuracy data before moving to downstream applications, requiring very few samples and still providing full spectrum information. In many cases, users only need a small sample such as cells, viruses, etc.
