ABSTRACT:
The present invention is directed to a method for separating mononuclear cells from other cells in a blood sample which is more rapid than the currently used density gradient material and which provides a better separation than methods utilizing thixotropic, gel-like material. In the method, a water soluble density gradient material is placed in a centrifuged tube. A water insoluble, thixotropic, gel-like substance is also placed in the container. A blood sample is placed in the container and the container is centrifuged for a time during which various components interchange positions and the gel-like substance forms a barrier between the mononuclear cells and the other cells of the blood sample.
