Abstract

A batch method for preparing polyacrylamide aqueous gels for electrophoresis, including providing a plurality of gel plate supporters abreast in an airtight gel-forming container, eliminating oxygen from or introducing oxygen-free gas into said container, charging a gel-forming solution into said container, and gelatinizing the solution. It can easily produce a large quantity of high quality polyacrylamide gel plates for electrophoresis with a homogeneous quality and a high resolving power in an automated batch method in a short period of time.

Claims4

Dependent claims

A batch method for preparing a polyacrylamide aqueous gel plate for electrophoresis comprising:

(1) placing a plurality of gel plate supporters in a gel-forming container which comprises:
(a) a partition rack comprised of plastic or rubber partition members which separate the gel plate supporters from each other,
(b) an inlet port,
(c) an outlet port, and
(d) an airtight lid;
(2) closing the airtight lid;
(3) eliminating oxygen from the container by evacuating air through the outlet port;
(4) charging a gel-forming solution into the container through the inlet port;
(5) allowing the gel-forming solution to gelatinize on the gel plate supporters;
(6) removing the partition rack from the container;
and
(7) removing the individual gel plates from the partition rack.
