title: A study of variability in the MHC class II beta 1 and class I alpha 2 domain exons of Atlantic salmon, Salmo salar L.
abstract: Variability in the most extracellular exons of Atlantic salmon MHC-Sasa class I and class II was studied by polymerase chain reaction (PCR) amplification followed by sequencing. The domains studied were class I alpha 2 and class II beta 1. The material used was genomic DNA of fish, mainly derived from the major Norwegian breeding pool, supplemented with some material from a minor breeder and a local river strain. The analysis revealed extensive variation, most individuals being heterozygous with at least two variants.
