用该冷冻-EM方法测定了伤寒毒素CDtB亚基上的B细胞表位图。伤寒毒素是伤寒沙门氏菌在感染过程中分泌的一种A2B5毒素。免疫球蛋白G(Ig G)直接与伤寒毒素混合,不同于我们以前使用Fab片段代替Ig G的冷冻-EM方法。这种简单的方法需要较少的材料,支持该方案的更广泛使用,以确定各种抗原上的抗体识别位点。有关本议定书的使用和执行的完整细节,请参阅和。本方案描述了确定抗体靶点的整个过程,以一对细菌AB毒素和毒素识别单抗对为例,可直接利用免疫球蛋白确定B细胞表位图。该方案为其他关于单抗-抗原复合体的研究提供了启示。该冷冻-EM方法用于确定伤寒毒素CDtB亚基上的B细胞表位图。伤寒毒素是伤寒沙门氏菌感染时分泌的一种A2B5毒素。免疫球蛋白G(Ig G)直接与伤寒毒素混合,不同于我们以前使用Fab片段代替Ig G的冷冻-EM方法。这种简单的方法需要较少的材料,支持该方案的更广泛使用,以确定各种抗原上的抗体识别位点。
This cryo-EM protocol was used to determine the B cell epitope map on the CdtB subunit of typhoid toxin, an A2B5 toxin secreted by Salmonella Typhi during infection. Immunoglobulin G (IgG) was directly mixed with typhoid toxin in this protocol, different from our previous cryo-EM protocol that uses the Fab fragments in place of IgG. This simple approach requires smaller amounts of materials, supporting the broader use of this protocol for determining antibody recognition sites on various antigens. For complete details on the use and execution of this protocol, please refer to and. This protocol describes the entire procedures for determining antibody target sites One bacterial AB toxin and toxin-recognizing mAb pair was used as an example IgG can be directly used to determine the B cell epitope map This protocol offers insights into other projects concerning mAb-antigen complexes This cryo-EM protocol was used to determine the B cell epitope map on the CdtB subunit of typhoid toxin, an A2B5 toxin secreted by Salmonella Typhi during infection.
