LC/MS Separation of Cholesterol and Sterols in Plasma

Detection of sterols using LC can be by MS, UV, or evaporative light scattering detection (ELSD). The choice of detector is influenced by the sensitivity needed in the separation, with LC/MS/MS providing very high sensitivity. We developed a method using MS with an Agilent 6460A triple quadrupole LC/MS and atmospheric pressure chemical

Effect of glycerol-induced DNA conformational change on

Oct 05, 2001Concluding remarks. DNA chains modified by glycerol have a larger contour length, a decreased effective charge over weight ratio, and a more uniform conformation. The separation of both dsDNA and ssDNA fragments is enhanced. This method is not applicable to high-speed separation due to the loss of migration time.

Agarose Gel Electrophoresis for the Separation of DNA

Apr 20, 2012Traditional agarose gels are most effective at the separation of DNA fragments between 100 bp and 25 kb. To separate DNA fragments larger than 25 kb, one will need to use pulse field gel electrophoresis 6, which involves the application of alternating current from two different directions. In this way larger sized DNA fragments are separated by the speed at which they reorient themselves with
