Abstract:
Antibodies or fragments thereof having CDR regions replaced or fused with biologically active peptides are described. Flanking sequences may optionally be attached at one or both the carboxy-terminal and amino-terminal ends of the peptide in covalent association with adjacent framework regions. Compositions containing such antibodies or fragments thereof are useful in therapeutic and diagnostic modalities.
Abstract:
Methods of making and selecting engineered antibodies and/or antibody fragments provide maximized binding affinity for a predetermined target and minimized immunogenicity when such antibodies are administered to a target species. Libraries containing variants of the engineered antibodies are also provided. In particularly useful embodiments, anti-PGDF antibodies and compositions are produced which are useful in the treatment of various cancers.
Abstract:
Methods of amplifying nucleic acid have now been discovered which include the steps of: a) annealing a primer to a template nucleic acid sequence, the primer having a first portion which anneals to the template and a second portion of predetermined sequence; b) synthesizing a polynucleotide that anneals to and is complementary to the portion of the template between the location at which the first portion of the primer anneals to the template and the end of the template, the polynucleotide having a first end and a second end, wherein the first end incorporates the primer; c) separating the polynucleotide synthesized in step (b ) from the template; d) annealing a nested oligonucleotide to the second end of the polynucleotide synthesized in step (b), the nested oligonucleotide having a first portion that anneals to the second end of the polynucleotide and a second portion having the same predetermined sequence as the second portion of the primer; e) extending the polynucleotide synthesized in step (b) to provide a terminal portion thereof that is complementary to the predetermined sequence; and f) amplifying the extended polynucleotide using a single primer having the predetermined sequence.
Abstract:
Domain-exchanged antibodies having CDR regions replaced or fused with biologically active peptides are described. Flanking sequences may optionally be attached at one or both the carboxy-terminal and amino-terminal ends of the peptide in covalent association with adjacent framework regions. Compositions containing such modified domain-exchanged antibodies are useful in therapeutic and diagnostic modalities.

In particularly useful embodiments, the methods are used to amplify a repertoire of IgA antibodies.
Abstract:
Expression vectors used for expression of mouse Fab libraries and expression of individual clones have portions of mouse constant regions replaced with human constant regions while maintaining desired cloning sites.
Abstract:
Human neutralizing antibodies (full-length or functional fragments) are useful as anti-toxins or anti-infectives with respect to infective agents such as, for example, anthrax, botulinum, smallpox, Venezuelan equine encephalomyelitis virus (VEEV), West Nile virus (WNV) and the like.
