To obtain the VLDLR fraction from the serum of a patient with type III hyperlipoproteinemia, we conducted ultracentrifugation and gel filtration. |
These results agree well with direct measurements of HDL's molecular mass by sedimentation ultracentrifugation. |
Currently, ultracentrifugation is the most common commercial method of purifying hemocyanin. |
After ultracentrifugation, the free peptide concentration was determined fluorometrically. |
Seven direct methods for measuring HDL and LDL cholesterol compared with ultracentrifugation reference measurement procedures. |
