  • Method for lysing hard liposomes using polyethyleneglycol mono-n-alkyl ethers
    Patent number: 5164320
    Abstract: A method for rapidly lysing liposomes having transition temperatures in the range of 35.degree. C. to 65.degree. C. is provided. Such liposomes are treated with a surfactant including polyethyleneglycol mono-n-alkyl ethers such as C.sub.12 H.sub.25 O(CH.sub.2 CH.sub.2 O).sub.n H where n=9-10, a nine mole ethylene oxide adduct of a blend of n-dodecanol, n-tetradecanol and n-hexadecanol, or other appropriate polyethyleneglycol mono-n-alkyl ether capable of causing rapid lysis. The method is applicable to fluorescence immunoassay procedures.
