应用细胞电泳技术,观察弓形体(ZS_2株)的细胞电泳率和表面电荷密度,结果表明在pH6.0～8.0时,弓形体的电泳率与表面电荷密度分别为-1.03～-0.85μ/s/v/cm和-3615.96～-4315.38esu/cm~2。在相同pH7.0条件下,经胰蛋白酶处理的弓形体电泳率(-1.82±0.11μ/s/v/cm)与对照组(-0.87±0.09μ/s/v/cm)相比,两组间的电泳率有明显差别,认为弓形体的表面阴性电离基团对胰蛋白酶敏感。 The cell electrophoretic rate and surface charge density of Toxoplasma gondii were observed by cell electrophoresis. The results showed that the electrophoretic rate and surface charge density of Toxoplasma gondii were between -1.03 and -0.85μ / s at pH 6.0-8.0 / v / cm and -3615.96 ~ -4315.38 esu / cm ~ 2. Compared with the control group (-0.87 ± 0.09μ / s / v / cm), the trypsin-treated toxoplasma electrophoresis rate (-1.82 ± 0.11μ / s / v / cm) Electrophoresis between groups was significantly different, that the surface of Toxoplasma negative ionizing group is sensitive to trypsin.
