Abstract

Abstract An electrophoretic apparatus comprising three electrode chambers serially arranged and filled with buffer solutions respectively, electrodes arranged in said electrode chambers respectively, three filter paper supports arranged above the spaces between the respective electrode chambers and above the central electrode chamber, a filter paper mounted on the central filter paper support and having both ends dipped into the buffer solution contained in the central electrode chamber and filter papers mounted on the other two filter paper supports and dipped at one end into the buffer solutions contained in the other electrode chambers. Said electrophoretic apparatus is so adapted as to form electrophoretic patterns of respective sera by electrically energizing a carrier onto which the sera are applied in two rows and which is mounted on said filter paper supports.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 116 words
An electrophoretic apparatus comprising at least two electrode chambers filled with buffer solutions respectively, electrodes arranged in said electrode chambers respectively, three filter paper supports, and three members for supplying said buffer solutions and electric current which are mounted on said filter paper supports respectively and dipped at one end into the buffer solutions contained in said electrode chambers, and so adapted as to form electrophoretic patterns by electrically energizing a carrier on which sera are applied in two rows after placing said carrier on said members for supplying the buffer solutions and electric current in such a manner that the portions of the carrier free from the sera are brought into contact with said members.
Claim 2
Dependent Claim 116 words
An electrophoretic apparatus comprising at least two electrode chambers filled with buffer solutions respectively, electrodes arranged in said electrode chambers respectively, three filter paper supports, and three members for supplying said buffer solutions and electric current which are mounted on said filter paper supports respectively and dipped at one end into the buffer solutions contained in said electrode chambers, and so adapted as to form electrophoretic patterns by electrically energizing a carrier on which sera are applied in two rows after placing said carrier on said members for supplying the buffer solutions and electric current in such a manner that the portions of the carrier free from the sera are brought into contact with said members.
Claim 3
Dependent Claim 82 words
An electrophoretic apparatus according to claim 1 wherein said electrode chambers are formed in a number of three, the one of said three members for supplying the buffer solutions and electric current which is arranged on the central filter paper support is dipped at both ends thereof into the buffer solutions contained in the central electrode chamber, and the other two members are dipped at one end thereof into the buffer solutions contained in the electrode chambers located on both sides respectively.
Claim 4
Dependent Claim 83 words
An electrophoretic apparatus according to claim 1 wherein said electrode chambers are formed as two outside and inside electrode chambers, the one of said three members for supplying the buffer solutions and electric current which is mounted on the central one of said three filter paper supports is dipped at both ends thereof into the buffer solution contained in said inside electrode chamber, and other two members are dipped at one end thereof into the buffer solution contained in said outside electrode chamber.
Claim 5
Dependent Claim 20 words
An electrophoretic apparatus according to claim 1 additionally comprising carrier clamps to be placed on said filter paper supports respectively.
Claim 6
Dependent Claim 22 words
An electrophoretic apparatus according to claim 4 comprising a cover having protrusions to be brought into contact with said carrier clamps respectively.
Claim 7
Dependent Claim 17 words
An electrophoretic apparatus according to claim 5 wherein said carrier clamps are formed integrally with said cover.
Claim 8
Dependent Claim 21 words
An electrophoretic apparatus according to claim 1 wherein said members for supplying the buffer solution and electric current are filter papers.
Claim 9
Dependent Claim 47 words
An electrophoretic apparatus according to claim 1 wherein the central one of said three filter paper supports is made of a foamed material (porous material) and serves also as the member for supplying buffer solution and electric current which is mounted on the central filter paper support.
