Abstract: A synthetic DNA library or a member of a synthetic DNA library of antibodies or fragments of antibody molecules having heavy chain(s) and lacking light chain(s) is described wherein the CDR within variable domains are synthesized using randomly assembled trinucleotide phosphoramidites (trimer phosphoramidites) to eliminate unwanted cysteine amino acids and/or stop codons.
Abstract: Described are polynucleotide sequences that encode peptide affinity tags with the surprising property that all of the possible out-of-frame peptide sequences are identical to each other, yet are distinct from the in-frame encoded peptide tag. The present invention includes peptide affinity tags incorporated in expressed proteins. Also described are ligands and antibodies that recognize the in-frame peptides and separate ligands or antibodies that recognize the out-of-frame peptides.
Abstract: A method of binding a protein to its encoding nucleic acid is disclosed wherein the method of binding is non-covalent at one or more locations between the protein and the encoding nucleic acids.
