Ulrich K. Laemmli

  (Redirected from Ulrich Laemmli)

Ulrich K. Laemmli is a Professor in the biochemistry and molecular biology departments at University of Geneva. He is known for the refinement of SDS-PAGE, a widely used method for separating proteins based on their electrophoretic mobility.[1] His paper describing the method is among the most cited scholarly journal articles of all time.[2][3][4] His current research involves studying the structural organization of nuclei and chromatin within the cell.[5]

Scientific career

Major scientific contributionsEdit

Although electrophoresis was used to separate proteins before Laemmli's work, he made significant improvements to the method. The term "Laemmli buffer" is often used to describe an SDS-containing buffer that is used to prepare (denature) samples for SDS-PAGE.[1][6]
