In a recent paper, Daveloose et al. (Daveloose, D., Fabre, G., Berleur, F., Testylier, G. and Letterrier, F. (1983) Biochim. Biophys. Acta 763, 41-49) described a technique to measure the internal microviscosity of erythrocytes using the spin label MAL-3 (2,2,5,5-tetramethyl-3-malimidopyrrolidinyl-N-oxyl)
