METHOD OF SELECTION OF A POPULATION OR SUBPOPULATION OF A SAMPLE

摘要

A separation procedure for separating a selected desired or undesired population from a biological sample utilizing relatively heavy, dense particles and gravity sedimentation. The particles have one or more reactants bound thereto which are specific to and will bind with the selected population. The particles preferably are mixed with the sample by repeatedly causing the particles to settle through a substantial portion of the sample to bind to the selected population. The particles with the bound selected population then are allowed to preferentially settle in the sample and the supernatant including the non-selected population is separated from the particles with the selected population bound thereto. The particles can be heated for sterilization and endotoxin removal.
