Abstract
The resolving power of 2-dimensional (2-D) gel electrophoresis was tested using 17 allele products at 5 loci. Standard O''Farrell gels could separate 13 of these isozymes. The addition of a 2nd pH gradient made it possible to separate all but 1 of the variant proteins. 2-D gel electrophoresis can resolve more than 90% of variants originally detected by 1-dimensional (1-D) electrophoresis. The implications of these results for the low estimates of average heterozygosity obtained in surveys using 2-D gel electrophoresis are discussed.
