Nine variant specific surface antigens were purified from clones of Trypanosoma equiperdum and characterized by amino acid analysis, isoelectric focusing and circular dichroism. The molecules showed extensive differences in their isoelectric points, and by comparison with the corresponding amino acid compositions, this variation seemed to be due to different amide contents. Circular dichroism data allowed one to divide the molecules into 4 groups according to their respective percentages in alpha-helical and beta-sheet structure.
从马媾疫锥虫克隆株中纯化出9种变体特异性表面抗原，并通过氨基酸分析、等电聚焦和圆二色性进行表征。这些分子的等电点存在广泛差异，与相应的氨基酸组成相比，这种差异似乎是由于酰胺含量不同所致。圆二色性数据使人们能够根据它们在α-螺旋和β-折叠结构中的各自百分比将这些分子分为4组。
