Abstract:
The invention provides compositions, methods and kits for high speed, high resolution of analytes by capillary electrophoresis starting with uncoated capillaries. The compositions comprise a sieving component, comprising a non-crosslinked acrylamide polymer, and a surface interaction component, comprising at least one uncharged and non-crosslinked water-soluble silica-adsorbing polymer. Methods for employing the novel compositions in capillary electrophoresis are provided. Kits comprising the novel compositions for use in the novel methods are also provided.

Claim (Index 57):
A composition for separating analytes by capillary electrophoresis comprising:\n a sieving component comprising a non-crosslinked acrylamide polymer having a weight average molecular weight between about 6,400,000 Da and less than or equal to about 25,000,000 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 the 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 surface interaction component is present in the composition at a concentration in the range of about 0.01% to about 1% w/w; wherein the sieving component and the surface interaction component differ in polymer chemical composition; and wherein the composition does not include a crosslinked polymer gel.
