Tiselius apparatus


Ti·se·li·us ap·pa·ra·tus

(tē-sā'lē-ŭs), an apparatus for separating proteins in solution by electrophoresis and thus for determining the isoelectric point, molecular weight, and related physical properties; the direction and rate of migration of the protein and the characteristics of the boundary phase between the protein solution and the supernatant salt solution are recorded by photography of the changes in refractive index at the boundary.
