  • Patent number: 9670483
    Abstract: Antigen-specific immunoglobulin V-regions are identified from a library of nucleic acids amplified using polymerase chain reaction using leader sequence-specific forward primers. The use of leader sequence primers allows all V-region sequences to be amplified (including those with extensive 5? end mutations) without loss of the original 5? V gene segment sequence. These libraries can be screened for antigen-specific V-regions using eukaryotic cells engineered to express the amplified V-region-encoding nucleic acids or using bacterial phage display techniques. In the latter, a second V-region library is made using a larger than conventional set of 5? V-region primers. The sequence errors introduced into the amplification products by this method are corrected using sequence information obtained in the products amplified by the V-region primers to screen the library created using the leader sequence primers.
