title: A rapid method for the preparation of the neutrophil fraction of granulocytes from human blood by centrifugation on isotonic Nycodenz gradients.
abstract: A rapid method for the preparation of neutrophils of the granulocyte fraction of human blood is described. A leucocyte-rich fraction is loaded onto preformed isotonic Nycodenz gradients, formed by mixing a stock isotonic Nycodenz solution with a NaCl diluent solution. After low speed centrifugation a neutrophil fraction of high viability, yield and purity can be isolated from the gradients.
