Separation of proteins using supramolecular gel electrophoresis

An amphiphilic low-molecular-weight hydrogelator 1 was synthesized. A tris-glycine-SDS solution gel of 1 was applied for electrophoresis to separate proteins. Centrifugation of a mixture of protein and a hydrogel of 1 enabled the recovery of protein. Various combinations of proteins were applied for supramolecular gel electrophoresis (SUGE), and remarkably poor mobility for small proteins (<45 kDa) was found.
