The application of oligonucleotide probes to HLA Class II typing of the DRB sub‐region

Abstract

A plan for DRB typing at the sequence level is detailed. Only one polymerase chain amplification reaction is needed and the application of a limited number of short oligonucleotide probes allows an almost complete definition of DRB alleles. The scheme was tested on 40 homozygous cell-lines selected to cover a wide range of specificities, and 40 RFLP-typed controls. The results are presented and discussed. The simplicity and accuracy of this scheme are emphasized.
