Human high density lipoprotein (HDL), 10 mg
Human High Density Lipoprotein. HDL is isolated from fresh human serum by sequential isopycnic ultracentrifugation at the lower and upper density limits of the specified density range. Density adjustments are performed with solid KBr. HDL is washed by centrifugation at the upper density limit to ensure removal of higher density proteins. HDL is filtered through a 0.45 µm filter and packaged aseptically.
