Evaluation of immunobiological properties of recombinant atoxic forms of the Pseudomonas aeruginosa exotoxin. MATERIALS AND METHODS. 3 recombinant atoxic forms of the P. aeruginosa exotoxin A were produced and studied: aTox1, consisting only of exotoxin A domain 1; aTox1,2, consisting of domain 1 and 2; and aTox1,2,delta3, consisting of both domain 1 and 2, and part of domain 3.
aToxl,2 and aTox1,2,delta3 had distinctive antigenic properties. Formulations based on these recombinant proteins were immunogenic and protected animals from exotoxin A in experimental conditions.
These results maybe used to construct direct-action immunobiological formulations.
评估铜绿假单胞菌外毒素重组无毒形式的免疫生物学特性。材料与方法。制备并研究了3种铜绿假单胞菌外毒素A的重组无毒形式:aTox1,仅由外毒素A结构域1组成;aTox1,2,由结构域1和2组成;以及aTox1,2,delta3,由结构域1和2以及部分结构域3组成。
aTox1,2和aTox1,2,delta3具有独特的抗原特性。基于这些重组蛋白的制剂具有免疫原性,并在实验条件下保护动物免受外毒素A的侵害。
这些结果可用于构建直接作用的免疫生物学制剂。
