Fig. 25. Identification of esterase loci illustrating the diversity of diagnostic locus EST2 in muscle homogenates. Top. Gel stained with 4­methyl­umbelliferyl butyrate, a substrate that enhances the activity of EST1 and minimizes that of EST2. Bottom. Opposite half of the same gel stained with 4 methyl­umbelliferyl acetate, a substrate that enhances the activity of EST2. The a­allele of EST2 is diagnostic for marmoratus; the b­allele is diagnostic for punctilinealis. Note that alleles for EST1 are mislabeled, owing to discovery of the rare a­allele (table 22) after labeling of this figure. Therefore, in this figure read the a­allele of EST1 as b, and read the b­allele as c, to be consistent with table 6. These fluorescent banding patterns were photographed in ultraviolet light; arrows indicate sites of sample application; anode is to the right.
