Restriction fragment-length polymorphism analysis of the major histocompatibility complex in New Zealand white...

As a model system, rabbits are particularly useful in transplantation studies because of their size and accessibility. However, inbred rabbits of known MHC haplotype are not commercially available, and there are few monoclonal antibody reagents available to permit serological typing of experimental animals prior to transplant. Here we present a rapid and reliable method to distinguish rabbits that differ at their MHC class I and class II loci, and present 34 class I and 16 class II haplotypes determined by restriction fragment-length polymorphism analysis of outbred heterozygous rabbits. The applicability of this molecular typing system to transplantation experiments in the New Zealand White rabbit is discussed.
