20090308751 | WELDED ELECTROPHORESIS CASSETTE WITHOUT LEAKAGE-PRONE WELD LINE - 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. | 12-17-2009 |
20100051462 | HYDROLYSIS-RESISTANT POLYACRYLAMIDE GELS - 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. | 03-04-2010 |
20100187114 | HIGH-PERFORMING ELECTROPHORESIS GELS WITH EXTENDED SHELF LIVES - 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. | 07-29-2010 |
20100213060 | AQUEOUS TRANSFER BUFFER - The present invention relates to an aqueous transfer buffer that provides superior efficiency in transferring polypeptides of a broad range of molecular weight from a matrix used in electrophoresis to another immobilized surface. Also disclosed are electrophoretic methods and devices in which the aqueous transfer solution of this invention is used. | 08-26-2010 |
20120285830 | HYDROLYSIS-RESISTANT POLYACRYLAMIDE GELS - 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. | 11-15-2012 |
20130056909 | DIMENSIONAL STABILIZATION OF SLAB GEL CASSETTES TO PREVENT DISTORTION CAUSED BY SWELLING GELS - Slab gel cassettes for use in electrophoretic analyses of biologically-derived mixtures are equipped with features that prevent the plastic walls of the cassettes from bowing outward when gels retained within the cassettes swell, as gels typically do during casting, storage, or both. In certain embodiments, these features are incorporated into, or mate with, the comb-shaped inserts that form the sample wells as the gels are being cast. In other embodiments, these features are complementary features incorporated into both the comb and the cassette. | 03-07-2013 |
20140014514 | AQUEOUS TRANSFER BUFFER - The present invention relates to an aqueous transfer buffer that provides superior efficiency in transferring polypeptides of a broad range of molecular weight from a matrix used in electrophoresis to another immobilized surface. Also disclosed are electrophoretic methods and devices in which the aqueous transfer solution of this invention is used. | 01-16-2014 |
20140138248 | POLYACRYLAMIDE ELECTROPHORESIS GELS WITH PROTECTION AGAINST OXYGEN EXPOSURE - The detrimental effect of oxygen exposure on the formation of polyacrylamide electrophoresis gels in oxygen-permeable plastic cassettes is reduced or eliminated either by the use of an oxygen barrier material over the surfaces of the plastic walls of the cassette through which oxygen would otherwise pass into the cassette cavity, or by the incorporation of an oxygen scavenger in the plastic from which the cassette walls are made, or both. | 05-22-2014 |
