Abstract

Alkali-treated lipopolysaccharide from Brucella abortus S1119.3 coupled to agarose beads by cyanogen bromide activation resulted in an immunoadsorbent with which a large amount of B. abortus-specific antibodies could be purified. The method described gave alkali-treated lipopolysaccharide binding efficiencies of up to 98%. There was little loss of alkali-treated lipopolysaccharide from the column after several pH shifts, allowing the immunoadsorbent to be regenerated and used repeatedly.

摘要

经碱处理的流产布鲁氏菌S1119.3脂多糖通过溴化氰活化偶联到琼脂糖珠上,得到一种免疫吸附剂,利用该免疫吸附剂可纯化大量流产布鲁氏菌特异性抗体。所述方法使碱处理的脂多糖结合效率高达98%。经过几次pH值变化后,柱中碱处理的脂多糖损失很少,使得该免疫吸附剂能够再生并重复使用。
