Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
A method for rapid molecular transfer without immersion in a buffer solution which comprises: providing an electrophoretically resolved material in a gelatin sheet; placing said gelatin sheet in contacting relationship with an immobilizing material to form a sheet-material combination; sandwiching said sheet-material combination between two plate electrodes in direct face-to-face relationship therewith to form an assembly; and applying electric current to said electrodes to provide transfer of electrophoretically resolved material to the immobilizing material without immersion in a buffer solution and in short periods of time.
Claim 2
Independent Claim
86 words
A method for rapid molecular transfer without immersion in a buffer solution which comprises: providing an electrophoretically resolved material in a gelatin sheet; placing said gelatin sheet in contacting relationship with an immobilizing material to form a sheet-material combination; sandwiching said sheet-material combination between two plate electrodes in direct face-to-face relationship therewith to form an assembly; and applying electric current to said electrodes to provide transfer of electrophoretically resolved material to the immobilizing material without immersion in a buffer solution and in short periods of time.
Claim 3
Dependent Claim
11 words
The method of claim 1 wherein said immobilizing material is paper.
Claim 4
Dependent Claim
11 words
The method of claim 1 wherein said immobilizing material is nylon.
Claim 5
Dependent Claim
17 words
The method of claim 1 wherein said sheet-material combination is in contacting relationship with said plate electrodes.
Claim 6
Dependent Claim
24 words
The method of claim 1 wherein a small amount of a non-reactive, conductive buffer solution is placed between the plate electrodes and sheet-material combination.
Claim 7
Dependent Claim
11 words
The method of claim 1 wherein said assembly is horizontally disposed.
Claim 8
Dependent Claim
12 words
The method of claim 1 wherein said plate electrodes are flat plates.
Claim 9
Dependent Claim
13 words
The method of claim 7 wherein said plate electrodes are flat carbon plates.
Claim 10
Dependent Claim
16 words
The method of claim 1 wherein said plate electrodes include holes therein for release of gases.
Claim 11
Dependent Claim
16 words
The method of claim 1 wherein said plate electrodes include grooves therein for release of gases.
Claim 12
Dependent Claim
21 words
The method of claim 1 wherein said plate electrodes are able to conduct amperages as high as 20 amps without heat-up.
Claim 13
Dependent Claim
12 words
The method of claim 1 wherein said assembly is placed under compression.
