Filed:

Sep 1, 2009

Appl. No.:

12/552104

Inventors:

Craig Rowell - Albany CA, US
Cory Panattoni - Winters CA, US
Thomas R. Berkelman - Oakland CA, US
Sean Cater - Oakland CA, US
Shane Petersen - Fairfield CA, US
Lee Olech - Pinole CA, US

Assignee:

Bio-Rad Laboratories, Inc. - Hercules CA

International Classification:

G01N 27/447

US Classification:

204468, 204456, 204606

Abstract:

Polyacrylamide gels that offer high resolution in protein separations and are more stable relative to hydrolysis than conventional polyacrylamide gels that rely on Tris or Tris-Bis as buffering agents are made by incorporating triethanolamine in place of most or all of the Tris or Tris-Bis.

Filed:

Appl. No.:

12/437698

Inventors:

Glenn Price - Martinez CA, US
Cory Panattoni - Winters CA, US
Craig Rowell - Albany CA, US
Shane Petersen - Fairfield CA, US
Evelio Perez - Richmond CA, US

Assignee:

BIO-RAD LABORATORIES, INC. - Hercules CA

International Classification:

G01N 27/447

US Classification:

204616

Abstract:

A slab gel cassette is formed from generally flat plates welded together along their borders with a gel space between the plates that is open at the top and bottom edges of the plates to expose the opposing ends of a gel in the gel space to buffer solutions in which electrodes are immersed. The plates are shaped such that the weld line does not intersect with the bottom opening of the gel space. Sealing of the bottom of the gel space, which is necessary for gel casting, is achieved by placing a sealing strip over the bottom opening with no danger of leakage of the gel solution along a weld line.

Assignee:

BIO-RAD LABORATORIES, INC. - Hercules CA

International Classification:

C07K 1/26
G01N 27/447

US Classification:

204470, 204469

Abstract:

Polyacrylamide gels that offer high resolution as electrophoretic media for protein separations and an improved resistance to hydrolysis upon storage are made by including either taurine, asparagine, or both as an ampholyte, in combination with either tris(hydroxymethyl)-aminomethane or bis(2-hydroxyethyl)amino-tris(hydroxymethyl)methane as a buffer, plus other conventional components.
