WebMay 19, 2016 · 19F-NMR has proved to be a valuable tool in fragment-based drug discovery. Its applications include screening libraries of fluorinated fragments, assessing competition among elaborated fragments and identifying the binding poses of promising hits. By observing fluorine in both the ligand and the target protein, useful information … WebSmall DNA molecules move more quickly through the gel than larger DNA molecules. The result is a series of ‘bands’, with each band containing DNA molecules of a particular size. The bands furthest from the start of the gel contain the smallest fragments of DNA. The bands closest to the start of the gel contain the largest DNA fragments.

WebJul 21, 2024 · A DNA marker (also known as a size standard or a DNA ladder) is loaded into the first well of the gel. The fragments in the marker are of a known length so can be used to help approximate the size of the fragments in the samples. The prepared DNA samples are then pipetted into the remaining wells of the gel.
