The collected infranatant fraction is then brought back to its original volume, and the cholesterol content is then measured by the Abell-Kendall method.
The infranatant containing immature adipocytes was discarded and then the remained mature adipocytes were collected.
Therefore, the analysis of the clear infranatant solution after ultracentrifugation will not give accurate triglyceride results.
We calculated the LDL-C concentration as the difference in the infranatant between TC and HDL-C (see online Supplemental Data).
006 kg/L and removal of the supernatant containing chylomicrons and VLDL, apoB (designated LDL apoB) was measured in the infranatant using 3 commercially available reagents each with antibodies to different apoB epitopes on automated chemistry analyzers.
To do this, we used sequential flotation ultracentrifugation for stepwise isolation of highly purified lipoprotein fractions (Athens Research and Technology), as described previously (6), with the exception that we also prepared IDL and lipoprotein particle-free infranatant fractions.
006 kg/L by ultracentrifugation (18 h; 105 000g; 4[degrees]C), and HDL-C was measured in the infranatant by the direct method (instead of precipitation).
006 kg/L by ultracentrifugation (at 105 OOOg for 18 h at 4 [degrees]C) and measuring HDLc after precipitation in the infranatant with phosphotungstate/ Mg[Cl.
LDLC was calculated as the difference between cholesterol in the infranatant before and after precipitation, measured as described above.
The floating layer containing VLDL and chylomicrons (if present) was removed, and the infranatant was reconstituted to known volume and analyzed for cholesterol using the enzymatic cholesterol assay.
21 kg/L for 48 h and extensive dialysis of the infranatant against 9.
