- #104 Separating Chlorophyll Pigments By Thin Layer Chromatography (tlc)
Chromatography is a method of separation that relies on the different solubilities of different solutes in a solvent. A mixture of chlorophyll pigments is dissolved in a solvent, and then a small spot is placed onto chromatography paper. The solvent gradually...

Coined/History
The first description of an electrophoric equipment was in 1937 in the paper ?A new Apparatus for Electrophoretic Analysis of Colloidal Mixtures? written by Arne Tiselius (1902 ? 29 October 1971). The equipment was finally developed in 1955 by British-born American geneticist and Nobel Laureate Oliver Smithies (1925- ) trying to separate insulin using moist starch grains which do not absorb proteins instead of moist filter paper of Kunkel and Sla ter in 1952. In his Nobel lecture in 2007 noted ? when I was a boy I sometimes helped my mother with the laundry, and remembered that the boiled starch she used for my father?s shirts set into a jelly when it was cold.?
Definition
Electrophoresis is the migration (or the equipment used for this) of electrally charged particles (such as proteins or nucleic acids) through a medium (gel or paper) under influence of an electric field.
