A method of obtaining nucleic acid encoding a plurality of antibodies is provided. In certain embodiments, the method comprises obtaining from an immunized animal nucleic acid encoding the amino acid sequence of the heavy and light chains of a second antibody that binds to the antigen as a first antibody and differs in amino acid sequence to the first antibody, wherein the obtaining is done by amplification using: i. a first primer pair that includes oligonucleotides are complementary to CDR-encoding regions first antibody.
