Esterase D Polymorphism in Galicia (North-West of Spain)

Abstract

Esterase D polymorphism has been studied by means of starch gel electro-phoresis in 543 unrelated subjects from the population of the North-West of Spain. The gene frequencies found were, EsD¹ = 0.8913, EsD² = 0.1087. The phenotype distribution was in good agreement with the Hardy-Weinberg equilibrium.

“…Determination of the EsD phenotypes was performed on starch gel using two different buffer systems: the buffer system (pH 8.6) described by Ashton et al [1] and the citratephosphate buffer system at pH 6.3 described by Swal low and Harris [21]. The isozymes were stained by a method similar to that reported by Caeiro et al [5], PGM, phenotypes were determined on starch gel using the electrophoretic conditions described by Spencer e t al. [19] and on PAG IF.…”
