A comparison of the isoenzymes, soluble proteins, polypeptides and free amino acids from ten isolates of Trypanosoma evansi

Abstract 1. 1. Soluble extracts from different strains of Trypanosoma evansi were compared by several analytical procedures. 2. 2. No isoenzymic differences were detected. 3. 3. Some clear intraspecies differences in protein isoelectric points, in polypeptide sizes and in free amino acid contents were found.
