Patent GB-950042-A (GB)
Title: Electrophoresis apparatus and system
IPC: G01N27/447
Filed: 1962-03-08
Abstract: <PICT:0950042/C3/1> An electrophoretic apparatus having a chamber in which a sample liquid is subjected to electrophoretic treatment characterized by the formation of a liquid density gradient in said chamber above said liquid sample layer to receive ingredients or ions separated by the electrophoresis at different density levels of said density gradient. Sample liquid or a series of samples of an ampholyte or a mixture of ampholytes, e.g. a protein or a mixture of proteins, is introduced as a stream into electrophoresis cell 10, through sample tube 34, together with several streams of buffer liquids of different specific gravities entering through tubes 24, 26, 28, 30, 32, 36 and 38 to form the density gradient above and supporting the thin layer of sample liquid.  The specific gravity of the sample liquid is not greater than the specific gravity of the buffer solution below the sample and is greater than the specific gravity of the buffer solution above the sample liquid.  After the liquid flow is interrupted a D.C. electric potential is applied across the cell between carbon electrodes 60 and 62, which are immersed in conducting electrolyte 21 and 14, and through semi-permeable membrane, 68 and 70.  The potential produces electrophoretic fractionation of the sample liquid, said fractionated liquid sample being scanned by ultra-violet light in the examination of proteins.  This cycle is repeated for each liquid sample with intervening flushing of the cell between successive samples by transmitting streams of the buffer through the cell and part of the next sample liquid between successive cycles.  The density gradient created by buffer solutions of different specific gravity, formed by adding varying amounts of sucrose solutions or glycerine to a standard buffer, is thus analyzed for the electrophoretically separated ingredients therein, by scanning the density gradient as with ultra-violet light and simultaneously recording quantitative measurement of the electrophoretically separated ingredients.  The cell 10, preferably formed of transparent plastic, is moved vertically in relation to the static light source in order to scan the density gradient.  Three scanning operations are performed; scan 1 confirms the presence of the sample in the cell and the quality of the sample zone before the application of the voltage, scan 2 is performed during the voltage application for the electrophoretic fractionation and scan 3 is performed to check complete fractionation.  The apparatus is applied to the separation of the blood serum proteins, for instance into the fractions albumin, alpha-globulin, beta-globulin, gamma-globulin and their subfractions. Specifications 817,070, 827,925, 834,635 and 874,855 are referred to.
