An anti-human NGF antibody Fab fragment comprising a heavy-chain fragment consisting of the amino acid sequence shown by SEQ ID NO:5 and a light-chain consisting of the amino acid sequence shown by SEQ ID NO: 8.

Provided herein is an improved method of antibody affinity maturation that uses true natural CDRs from a population of naturally occurring antibodies targeting a single antigen or antigenic epitope such that the improved method produces functional antibodies having low-picomolar affinity antibodies. Also provided herein is an antibody library where the CDRs within a single antibody member of the library are a combination of CDR sequences of naturally occurring antibodies and one or more CDRs are derived from different naturally occurring antibodies targeting a single antigen or antigenic epitope.
