Original Article


The field isolates of Trypanosoma evansi was collected from the infected cattle and it was propagated in rats. Trypanosoma evansi parasites were separated from the blood of infected rats by using diethylaminoethyl cellulose column chromatography. Whole cell lysate antigen (WCL) was prepared from purified trypanosomes by ultrasonication and centrifugation. The prepared WCL antigen was further purified by 50 % ammonium sulphate precipitation. Protein concentration of WCL antigen of T. evansi was 60 mg/ml. Protein concentration was adjusted to 1.0 mg/ml in PBS, pH 8.0 and stored at −200 C.   Polypeptide profiles of WCL antigen of T. evansi was determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis. A total of eight polypeptide bands of the size ranging from 25 to 85 kDa in WCL antigen of T. evansi were obtained. Five prominent bands with molecular weight of 74, 60, 53, 42 and 37 kDa and three light bands with molecular weight of 85, 34 and 25 kDa were observed.
