Iodixanol is also the active ingredient in a number of 'cushion' products used during the centrifugation of stallion semen. It is layered underneath the extended stallion semen allowing for a higher g force to be used with less sperm damage and better recovery rates. Post centrifugation the supernatant above and the cushion below is removed, leaving a concentrated sperm pellet in the conical tube. WebNeither differential centrifugation nor sucrose gradient confer the ability to separate exosomes (40–100 nm) from viruses because of their similarities in density and Author Manuscript size. Recently, a modified protocol involving separation on the iodixanol (optiprep™) gradient, was proposed.
