摘要:
The present invention provides methods, compositions, and kits for protein crystallization. The present invention involves electrophoretically focusing at least a first protein species within a matrix comprising at least 2 regions of different pH, the protein being present in amount sufficient to permit crystallization within said pH gradient.
摘要:
The invention relates to marker molecules for identifying physical properties of molecular species separated by the use of electrophoretic systems. The invention further relates to methods for preparing and using marker molecules.
摘要:
A multielevational cover for assembling a fluid retaining chamber on a face of an electrophoresis cassette is presented. The cover comprises a cassette-containing member, at least one chamber-defining member, and sealing means, typically sealing means that are capable of reversible attachment. Also presented are methods for contacting cassette-immobilized gels to desired fluids by assembling a fluid retaining chamber upon the cassette using the covers of the present invention.
摘要:
Provided herein are rapidly-rehydratable prior-cast, dehydrated, electrophoresis separation media particularly useful for isoelectric focusing, including methods of making, and methods of use thereof.
摘要:
Methods and apparatus are presented that facilitate electrophoresis of prior-cast, hydratable separation media, usefully immobilized pH gradient (IPG) strips. The method exploits the swelling of prior-cast, hydratable separation media upon rehydration to help lodge the media in an enclosing member that permits spaced electrical communication with the enclosed separation media. The electrical communication permits a voltage gradient to be established in the enclosed separation medium sufficient to effect separation of analytes therein. Cassettes, buffer cores, electrophoresis systems and kits are presented for effecting the methods of the invention.
