title: Cloning and sequencing of immunoglobulin variable-region genes using degenerate oligodeoxyribonucleotides and polymerase chain reaction.
abstract: A procedure is described for using the polymerase chain reaction (PCR) to amplify and clone the cDNA from mouse immunoglobulin (Ig) variable (V) regions. This method uses a set of universal 5'-oligodeoxyribonucleotide primers that are degenerate and allow for the amplification of Ig V-region sequences from gamma and mu heavy chains and from kappa light chains. Selective first-strand cDNA synthesis is performed using Ig constant region primers and then a PCR is achieved by using the appropriate universal 5'-primer. The universal Ig heavy-chain primer was used to amplify the V-region cDNA from gamma and mu isotypes and the universal light-chain primer was used to amplify three separate kappa light V-region sequences. This procedure was used to obtain Ig V-region gene sequences from hybridomas secreting IgG1/kappa, IgG2b/kappa and IgM/kappa isotypes.
