Abstract
Abstract A device for the horizontal electroblotting of electrophoretically transferred material comprising a fluid tight container having a floor, a lid and side walls extending between the floor and the lid for defining a chamber, a support assembly located in the chamber for supporting the material to be electroblotted, a first electrode provided below the support assembly and a second electrode provided above the support assembly and a barrier provided in the chamber between the first electrode and the support assembly for diverting bubbles produced by the first electrode so as to prevent the bubbles from accumulating on the support assembly during the electroblotting of the electrophoretically transferred material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
A device for the horizontal electroblotting of electrophoretically transferred material comprising a fluid tight container having a floor, a lid and side wall means extending between said floor and said lid for defining a chamber, a support assembly located in said chamber for supporting the material to be electroblotted, a first electrode provided below said support assembly and a second electrode provided above said support assembly and means provided in said chamber between said first electrode and said support assembly for diverting bubbles produced by said first electrode so as to prevent said bubbles from accumulating on said support assembly during the electroblotting of the electrophoretically transferred material wherein said means provided in said chamber between said first electrode and said support assembly comprises a membrane disposed in said chamber and spaced from said floor such that said membrane is disposed at an angle with respect to said floor.
Claim 2
Independent Claim
149 words
A device for the horizontal electroblotting of electrophoretically transferred material comprising a fluid tight container having a floor, a lid and side wall means extending between said floor and said lid for defining a chamber, a support assembly located in said chamber for supporting the material to be electroblotted, a first electrode provided below said support assembly and a second electrode provided above said support assembly and means provided in said chamber between said first electrode and said support assembly for diverting bubbles produced by said first electrode so as to prevent said bubbles from accumulating on said support assembly during the electroblotting of the electrophoretically transferred material wherein said means provided in said chamber between said first electrode and said support assembly comprises a membrane disposed in said chamber and spaced from said floor such that said membrane is disposed at an angle with respect to said floor.
Claim 3
Dependent Claim
42 words
