domestic rabbit, Oryctolagus cuniculus, by means of isoelectric focus
ing and immunoblotting. The analysis of 298 individuals, corresponding
to one French and two Portuguese populations, revealed the existence
of six alleles, of which BFA, B and C were common alleles, and D, F a
nd G were rare ones.
