Abstract

To the Editor: The letter by Poiesz attributing red-cell agglutinating activity to sodium diatrizoate (Hypaque)1 is not accurate. The technic of isolation of leukocytes from human blood as originally described by Böyum and mentioned by Mr. Poiesz does employ a Ficoll–Hypaque density-gradient system to aggregate red blood cells and accelerate separation from the mononuclear cells.2 The Ficoll and not the sodium diatrizoate, however, was reported by Böyum to be the red-cell aggregating agent. Ficoll, which is a sucrose polymer, shares this aggregating ability with other high polymer compounds, including dextran, hydroxyethylcellulose, methylcellulose, povidone (polyvinylpyrrolidone), fibrinogen, phytohemagglutinin and hexadimetrin bromide, all.
