Antibody diversity generation

   
   

Methods for improving antibodies by a variety of DNA diversification and selection procedures are provided. Improvements include increases in affinity, alterations in specificity and effector function, as well as reduced antigenicity, e.g. humanization. Libraries of recombinant antibody sequences are provided, as are cells expressing members of such libraries. Novel phage display vectors are provided. Methods for the coevolution of an antibody and its cognate antigen are provided. Coevolution is used to evolve HIV envelope proteins with increased antigenicity and broadly neutralizing antibodies that interact therewith. Methods of improving antibodies for use in the detection of biological warfare agents are provided.

Os métodos para melhorar antibodies por uma variedade de procedimentos da diversificação e de seleção do DNA são fornecidos. As melhorias incluem aumentos na afinidade, alterações no specificity e a função effector, as.well.as o antigenicity reduzido, por exemplo humanization. As bibliotecas de seqüências recombinant do antibody são fornecidas, como seja pilhas que expressam membros de tais bibliotecas. Os vetores phage da exposição da novela são fornecidos. Os métodos para o coevolution de um antibody e de seu antígeno cognate são fornecidos. Coevolution é usado evoluir as proteínas do envelope do HIV com antigenicity aumentado e os antibodies amplamente neutralizando que interagem therewith. Os métodos de melhorar antibodies para o uso na deteção de agentes da guerra biológica são fornecidos.
