Abstract
The present invention concerns a solid phase method for isolating and/or enriching predetermined cells from a sample. Such methods are used e.g. to isolate and enrich predetermined cells like fetal cells from a sample of maternal peripheral blood, tumor cells from a sample of body fluid or stem cells from a fluid or fluidized sample of body tissue or body fluid. The solid phase isolation method of the present invention is used for isolating predetermined cells from a sample containing such predetermined cells by binding the predetermined cells to a solid surface. According to the invention the sample is contacted with the solid surface and then removed from the solid surface, wherein the sample or a washing buffer contains a polyol during or after contacting the sample with the solid surface.
