Comparative study on the composition of platelets from the equine, bovine, ovine and porcine species

Abstract

It is concluded that there are few differences between the concentrations of total protein, total lipids and hexosamines in the blood platelets preparations obtained from the bovine, equine (horse, donkey, mule), ovine and porcine species; for hexoses some differences were noted in two species; with reference to sialic acids the difference varies with the type of the acids: an equal ratio for NGNA and NANA was found in the ovine specie, and NGNA was predominant in the other species (in contrast with the human specie in which only NANA seems to occur). The hydrolysis with V. choleras neuraminidase gave nearly similar results to those obtained by sulfuric acid hydrolysis.
