Study Notes
Electrophoresis
- Arne Tiselius published a paper on the complete process and applications of electrophoresis in 1937.
- The scientist who first reported evidence of electrophoresis was Arneus van Gijn.
- The main purpose of electrophoresis is to separate and analyze charged particles, such as proteins or DNA molecules, based on their size and charge.
- The size of the pore in agarose gel affects the movement of DNA molecules, with smaller pores slowing down the movement of larger DNA molecules.
- Arne Tiselius was awarded the Nobel Prize in Chemistry in 1948 for his research on electrophoresis and adsorption analysis.
