OLIGONUCLEOTIDE PRIMERS FOR POLYMERASE CHAIN-REACTION AMPLIFICATION OF HUMAN-IMMUNOGLOBULIN VARIABLE GENES AND DESIGN OF FAMILY-SPECIFIC OLIGONUCLEOTIDE PROBES

In recent work, the polymerase chain reaction (PCR) has been used to amplify rearranged mouse and human immunoglobulin heavy and kappa light chain variable (V) genes. Here we have optimized the design of the PCR primers for human V genes and used them to amplify cDNA from human peripheral blood lymphocytes. Cloning and sequencing revealed a diverse repertoire of V genes, and the presence of members of each human V gene family. After alignment of the sequences, we identified a region conserved within V gene families, but differing between families, and used this to design family-specific oligonucleotide probes.
