Coli mainly in a form of inclusion body. The expressed product contained about 25% of total somatic protein and showed good reactogenicity as proved by Western blot. The IgG level against GAMP induced by GAMP-CRM197 conjugate was significantly higher than those by GAMP and by the mixture of CAMP and rCRM197. Repeated immunization with the conjugate induced immunopotentiation, indicating the effect of CRM197 as a carrier protein.
结果重组CRM197在大肠杆菌中主要以包涵体形式表达,表达量占菌体总蛋白的25%左右;Western blot证明重组rCRM197具有良好的反应原性;各针接种后,结合物诱生的多糖特异性IgG水平均显著高于GAMP组和GAMP+rCRM197混合物组,具有较强的免疫原性;多次接种产生了免疫增强效应,重组CRM197具有载体蛋白的作用。

For most piercing-sucking insects, they will secrete gell saliva and watery saliva when they feed on plants. The gell saliva will be secreted at the early stage of feeding to form salivary sheath, which is supposed to surround and protect the stylet. This saliva can help piercing-sucking insects to feed on plants directly and indirectly. Meanwhile, the watery saliva contains many components like pectnase, cellulose, polyphenol oxidase, peroxidase, alkaline phosphatase, sucrase, etc. These components can help piercing-sucking insects in plant tissue penetration, food digestion, detoxification of plant secondary substances and break-down of plant defence reaction.
