Positive and negative selection of cells by hapten-modified antibodies

A method for simultaneous positive and negative selection of cells identified by an antibody is described. It is an adaption of the panning technique using anti-benzene arsonate (Ars)-coated Petri dishes to select the Ars-antibody-coated cells. The adherent cell population is recovered in a suitable state by hapten elution with Ars-azo-tyrosine.
