The change of agglutinating activity in different temperature and pH indicated that PML had no hemagglutinating activity at 80℃. The effect of chemical modification of amino acid residues upon hemagglutination was investigated. There was a definite decrease of fluorescence intensity which corresponds to the oxidation of tryptophan.

研究了不同温度、pH和变性剂对PML凝血活性的影响和荧光光谱的变化，当温度达80℃时，活性完全丧失；pH为4—9对活性影响不大，pH低于2和pH高于12时，大黑花芸豆凝集素的凝血活性大部分丧失；高温和强碱对荧光光谱有较大影响，表明PML对高温，强碱的耐受性不强。
