title: PCR-RFLP-based Mamu-DQB1 typing of rhesus monkeys: characterization of two novel alleles.
abstract: Up to now 19 allelic sequences of the rhesus monkey DQB1 locus have been published. Referring to these sequences, we have developed a typing protocol for Mamu-DQB1 alleles which was verified by additional cloning, sequence analysis and segregation studies. The protocol is based on the amplification of the second exon with only one specific primer pair followed by the digestion of the PCR products with up to 10 different restriction endonucleases. The alleles can be identified in homozygous and heterozygous combinations since most amplified second exon sequences give unique hand patterns after digestion with at least one of the selected restriction endonucleases. By the use of this protocol we analyzed DNA-samples from 182 rhesus monkeys. Among these samples two novel Mamu-DQB1 alleles were detected, subsequently cloned and their nucleic sequence determined. Since we typed four complete breeding groups consisting of two generations we were able to identify several DQ haplotypes by segregation analysis using the previously developed typing protocol for DQA1.
