Inthis work, the Vε and Vκ genes of the two clones weresequenced and their putative germline gene usages werestudied. On the basis of the known 3D structure of Trichosanthin and antibody, molecular modeling was carriedout to study the antigen-antibody interaction. The possible antigenic determinant sites on the surface of TCSrecognized by both the clones were analyzed, and the reaction forces between TCS and two Fab fragments werealso analyzed respectively.展开更多
