Einwirkung von Äthylenoxyden auf Lysozym

One mol. of lysozyme combined with 12 mots. of ethylene oxide at 4-5°C, pH 8.7, when magnesium ion existed. Lysozyme, after having reacted wi h ethylene oxide so thoroughly that amino groups were no more detectable, still did not alter in the lytic activity and UV-absorption. Only in the ionophoresis a different result appeared. This N-hydroxyethyl derivative of lysozyme behaved also almost equally with the native lysozyme in the oxidation by periodate.
