  • Polyacrylamide medium for the electrophoretic separation of biomolecules
    Patent number: 6646084
    Abstract: A polyacryalmide medium for the electrophoretic separation of biomolecules. The polyacryalmide medium comprises high molecular weight polyacrylamides (PAAm) having a viscosity average molecular weight (Mv) of about 675-725 kDa were synthesized by conventional red-ox polymerization technique. Using this separation medium, capillary electrophoresis of BigDye DNA sequencing standard was performed. A single base resolution of ˜725 bases was achieved in ˜60 minute in a non-covalently coated capillary of 50 &mgr;m i.d., 40 cm effective length, and a filed of 160 V/cm at 40° C. The resolution achieved with this formulation to separate DNA under identical conditions is much superior (725 bases vs. 625 bases) and faster (60 min. vs. 75 min.) to the commercially available PAAm, such as supplied by Amersham.
