Provided are oligonucleotides for isolating human antibody cDNAs from cells or cell lines, such as hybridomas. The invention also provides cDNAs that encode at least one provided CDR of a heavy chain or a light chain of a human monoclonal antibody that binds to B. anthracis protective antigen; and cDNAs that encode at least one provided CDR of a heavy chain or a light chain of a human monoclonal antibody that binds to B. anthracis lethal factor. The invention further provides expression vectors that contain one or more cDNAs isolated according to the methods of the invention, host cells expressing one or more inventive cDNAs, and transgenic plants and animals that express one or more inventive cDNAs. In certain embodiments of the invention the expression system is a plant-based expression system. The invention further provides antibody compositions comprising one or more antibodies produced by expressing a cDNA isolated according to the methods of the invention in a suitable expression system. Additionally encompassed in the invention are kits containing one or more of provided compositions, as well as methods of production and use of provided compositions.
