Traditional ultracentrifugation methods for purifying LDL, VLDL or HDL can be time consuming and inconvenient. Our LDL/VLDL and HDL Purification Kit uses dextran sulfate to selectively and separately purify LDL/VLDL and HDL fractions for a variety of downstream applications. No ultracentrifuge is necessary, and purification steps use lower centrifugation speeds available with most benchtop centrifuges.
