A simple method of obtaining an enriched fraction of tegumental brush border from Hymenolepis diminuta

Abstract

A method for isolating an enriched preparation of tegumental brush border from the tapeworm, Hymenolepis diminuta, is described. Combining incubation of whole tapeworms in Krebs-Ringer/tris-maleate solution containing a hemolytic saponin, low shear-force agitation, and differential centrifugation, a pellet is obtained at 2,500 g which contains a significant concentration of surface brush border. The content of brush border in this fraction is identified by the presence of numerous microvilli, increased specific radioactivity after surface tagging with 3H-Concanavalin A, and relatively little mitochondrial contamination (succinic dehydrogenase). Based on morphological criteria, fractions sedimenting with greater force contain dense vesicles and mitochondria from the outer portion of the tegument.
