A composition of matter and method for using the composition of matter to isolate various cell elements from a heterogeneous cell suspension in a simple one step procedure. The composition is a monoclonal antibody mixture including complement and a non-toxic density gradient media. The composition provides a negative selection technique in which undesired subpopulation cells are lysed and separated from the desired cell subpopulation.
