Agarose gel electrophoresis (AGE) is an approach that is used to distinguish DNA from RNA based on their molecular sizes.
The separation of RNA and DNA molecules is accomplished when nucleic acids that are negatively charged travel through an agarose structure under an influence of an electrical fields (electrophoresis).
Despite all the technical advances in scientific laboratories, the Neubauer Chamber is still the most widely used method for cell counting worldwide. This technical data sheet was created to assist experienced and novice researchers in performing a cell count using a Neubauer or Hemocytometer. These principles can be applied to any cell-counting chamber. However, the … Read more
