title: Development of a microassay technique for neutrophil adherence.
abstract: The development of a microassay for neutrophil adherence is described. The nylon fibre column consisted of 10 mg of fibre inserted into a micropipette tip. A vacuum harvester was constructed to aspirate the neutrophil-containing fluid in the columns into disposable test-tubes for quantitation of neutrophil concentrations. In this way, the neutrophil requirement was reduced from 10(7) cells to 10(5) cells. A complete assay can be performed efficiently and rapidly using less than 1 ml of blood.
