Characterization of Trypanozoon stocks by isoelectric focusing and isoenzyme analysis.

Isoelectric focusing on ultrathin polyacrylamide foils, coupled with isoenzymatic analysis using five different enzymes, was used to characterize blood-forms of T.b. brucei, T.b. rhodesiense and T.b. gambiense and procyclic forms of T.b. brucei and T.b. rhodesiense. The protein concentrations in the lysates were quantified. Qualitative as well as quantitative differences were found.
