Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
34 words
In an element for electrophoresis comprising a membrane medium for electrophoresis between a cover sheet and a support, the improvement in which the cover sheet has a thickness of not more than 50 µm.
Claim 2
Dependent Claim
34 words
In an element for electrophoresis comprising a membrane medium for electrophoresis between a cover sheet and a support, the improvement in which the cover sheet has a thickness of not more than 50 µm.
Claim 3
Dependent Claim
23 words
The element for electrophoresis as claimed in claim 1, in which the thickness of said cover sheet ranges from 3 to 50 µm.
Claim 4
Dependent Claim
23 words
The element for electrophoresis as claimed in claim 1, in which the thickness of said cover sheet ranges from 5 to 40 µm.
Claim 5
Dependent Claim
18 words
The element for electrophoresis as claimed in claim 1, in which said medium is a gel membrane medium.
Claim 6
Dependent Claim
23 words
The element for electrophoresis as claimed in claim 1, in which said support and cover sheet are both made of non-electroconductive, water-impermeable material.
Claim 7
Dependent Claim
33 words
The element for electrophoresis as claimed in claim 5, in which either of said support and cover sheet has a hydrophilic surface on at least a side in contact with the membrane medium.
Claim 8
Dependent Claim
29 words
The element for electrophoresis as claimed in claim 1, in which said support and cover sheet are sealed each other under adhesion at least at two corresponding side ends.
Claim 9
Dependent Claim
32 words
The element for electrophoresis as claimed in claim 7, in which a spacer having a thickness of not exceeding the thickness of the membrane medium is provided inside of the sealed end.
Claim 10
Dependent Claim
22 words
The element for electrophoresis as claimed in claim 8, in which said spacer is attached under adhesion to at least said support.
Claim 11
Dependent Claim
20 words
The element for electrophoresis as claimed in claim 8, in which said spacer and suppurt are molded into one piece.
Claim 12
Dependent Claim
28 words
The element for electrophoresis as claimed in claim 1, in which said membrane medium has at least one slot for introduction of a sample at one end thereof.
Claim 13
Dependent Claim
19 words
The element for electrophoresis as claimed in claim 11, in which said slot is covered with the cover sheet.
Claim 14
Dependent Claim
41 words
The element for electrophoresis as claimed in claim 11, in which said slot is covered with the cover sheet at a portion nearer to the electrophoretic separation area and other portion thereof is exposed with no covering of the cover sheet.
Claim 15
Dependent Claim
30 words
The element for electrophoresis as claimed in claim 1, in which a groove for a sample is provided on the membrane medium at a position near to one end thereof.
Claim 16
Dependent Claim
22 words
The element for electrophoresis as claimed in claim 14, in which said groove is exposed with no covering of the cover sheet.
Claim 17
Dependent Claim
33 words
The element for electrophoresis as claimed in claim 14, in which said groove is so covered with a portion of the cover sheet that said portion can be removed to expose the groove.
Claim 18
Dependent Claim
28 words
The element for electrophoresis as claimed in claim 4, in which said gel membrane medium is produced by gelation of a gel forming solution directly on said support.
