DONOR SPECIFIC ANTIBODY LIBRARIES
The present invention concerns donor-specific antibody libraries derived from a patient donor who has suffered from, or is suffering from one or more diseases discussed herein. The present invention also concerns the method of making and using the donor-specific antibodies. The present invention further concerns the neutralizing antibodies obtained from the donor-specific antibody libraries and the methods of using these antibodies for the prevention/treatment of human disease.

12 . The vector collection of claim 10 wherein at least part of said non-contiguous sequence is incorporated into the nucleic acid molecules encoding the antibody light or heavy chains or fragments thereof such that it does not interfere with the expression of said nucleic acid molecules.
13 . The vector collection of claim 1 wherein the barcode encodes peptide or polypeptide sequence.
14 . The vector collection of claim 1 wherein the vectors are phagemid vectors.
15 . The vector collection of claim 14 wherein the phagemid vectors contain a bacteriophage gene III and a stop codon between the nucleic acid molecules encoding antibody light or heavy chains or fragments thereof and the bacteriophage III gene.
16 . The vector collection of claim 15 wherein the nucleotide sequence barcode is a non-coding contiguous nucleotide sequence inserted in the untranslated region following said stop codon.
17 . Host cells comprising the vector collection of claim 1 .
18 . The host cells of claim 16 which are E. coli host cells.
19 . A pooled vector collection comprising a plurality of vector collections according to any one of claims 1 to 16 from different human donors, wherein different nucleotide sequence barcodes identify vectors or library members derived from the different donors.
20 . A pooled vector collection comprising a repertoire of nucleic acid molecules encoding antibody light or heavy chains or fragments thereof, derived from at least two human patient donors who have suffered from, or are suffering from, a disease evoking antibody production to a target antigen, wherein said collection is identified with a unique nucleotide sequence barcode that is linked to and labels said nucleic acid molecules in the vector.
