    摘要: The present invention is directed generally to compositions and methods for obtaining secretion of antibodies or antigen-binding antibody fragments from prokaryotes without the need for a signal peptide through making use of mutant host strains with altered secretory properties. In particular, the invention provides host cells and methods for obtaining secretion of antibodies or antigen-binding antibody fragments from bacteria without the need for a signal peptide and provides diverse libraries of antibody sequence resulting from such methods. The invention additionally provides diverse libraries.

    摘要: The invention provides methods for generating human antibodies with the specificity of a reference antibody by replacement of portions of the VH and VL sequences of the reference antibody with sequences from human antibody repertoires. The invention also provides novel compositions comprising hybrid immunoglobulin variable domains containing a combination of frameworks (FRs) and CDRs from different antibody clones.
