title: A new simplified single-filter assay for 'in vitro' evaluation of chemotaxis of 51Cr-labeled polymorphonuclear leukocytes.
abstract: A new simplified radioassay for measuring polymorphonuclear leukocyte (PMN) chemotaxis is proposed using 51Cr-labeled cells and a single-filter system. The technique offers all the advantages described for the double-filter radioassay and permits a reproducible measurement of random locomotion, chemokinesis and chemotaxis. Moreover the single-filter radioassay utilizes commercially available and disposable chambers gathered in a multichamber apparatus; this makes the method very easy to learn and rapid to perform.
