An endogenous heparin-binding lectin activity isolated from rat lung was separated into two distinct isolectin forms which showed subtle changes in carbohydrate specificity. The two lectin forms displayed different specificities toward alginic acid-purified cystic fibrosis isolates of Pseudomonas aeruginosa when assayed by inhibition of both hemagglutination and [3H]heparin binding. This ability of isolectin forms to show higher affinity toward alginic acid from certain P. aeruginosa strains may suggest that there is a selective mechanism in the colonization of patients with cystic fibrosis.
从大鼠肺中分离出的一种内源性肝素结合凝集素活性被分为两种不同的同工凝集素形式,它们在碳水化合物特异性上表现出细微变化。当通过抑制血凝和[3H]肝素结合进行测定时,这两种凝集素形式对藻酸纯化的铜绿假单胞菌囊性纤维化分离株表现出不同的特异性。同工凝集素形式对某些铜绿假单胞菌菌株的藻酸表现出更高亲和力的这种能力,可能表明囊性纤维化患者的定植存在一种选择性机制。
