Abstract:
A method for separating analytes by capillary electrophoresis comprising:separating the analytes by capillary electrophoresis in a composition comprising: a sieving component comprising a non-crosslinked acrylamide polymer having a molecular weight greater than 1,000,000 Da and less than or equal to about 3,000,000 Da; and a surface interaction component comprising one or more non-crosslinked polymers selected from the group consisting of poly(meth)acrylamide, N,N-disubstituted polyacrylamide and N-substituted polyacrylamide, wherein said N-substituents are selected from the group consisting of C1 to C3 alkyl, halo-substituted C1 to C3 alkyl, methoxy-substituted C1 to C3 alkyl, and hydroxyl-substituted C1 to C3 alkyl; wherein the sieving component and the surface interaction component are the same or different; and wherein the composition does not include a crosslinked polymer gel wherein the non-crosslinked acrylamide polymer has a viscosity of less than 1,000 centipose at 25Â° C.
