Hemolysis by Nonionic Surface-active Agents

open access: yesYAKUGAKU ZASSHI, 1966
The hemolytic actions of polyoxyethylene glycol monododecyl ethers, C12H25-(C2H4O)nOH, have been studied. The amount required of these agents to produce lysis was found to be linearly related to the red cell concentration within experimental error. This was interpreted as showing the significant role of the adsorption of nonionic agent molecules onto ...
