Editing Gel electrophoresis (section)

===Starch===

Partially [[hydrolysis|hydrolysed]] potato starch makes for another non-toxic medium for protein electrophoresis. The gels are slightly more opaque than acrylamide or agarose. Non-denatured proteins can be separated according to charge and size. They are visualised using Napthal Black or Amido Black staining. Typical starch gel concentrations are 5% to 10%.<ref name="Gordon1969">{{cite book | last=Gordon | first=A.H. | title=Electrophoresis of Proteins in Polyacrylamide and Starch Gels: Laboratory Techniques in Biochemistry and Molecular Biology | publisher=North-Holland Pub.
