Patent number: 6585873Abstract: A crosslinked hydrophilic gel in which the crosslinker used in a compound of Formula I or Formula II or combination thereof. These crosslinked hydrophilic gels provide enhanced separation in electrophoresis. The use of the crosslinkers of Formula I and/or II can result in electrophoresis gels having improved properties including: 1) a broader pore size range; 2) control of pore size distribution; 3) greater resistance to hydrolysis in alkaline media; 4) greater clarity of gels prepared with high concentration of the crosslinkers; and 5) improved background silver staining.Type: GrantFiled: March 22, 2000Date of Patent: July 1, 2003Assignee: University of MelbourneInventors: David Henry Solomon, Greg GuangHua Qiao, Georgia Patras
