【摘要】 用细胞电泳技术,对两株溶组织内阿米巴在pH梯度中的细胞电泳及伪足形成情况进行观察。结果表明:随着pH值变大,电泳速度加快,伪足出现率也增多,两者之间具有显著的相关性。提示阿米巴的伪足运动可能与其质膜的电荷变化有关。更多还原

【Abstract】 In this paper, cell electrophoretic mobility (EPM) and the appearance of pseudopodia in two Entamoeba histolytica strains under gradient pH is reported.Using cell electrophoretic techniques, in two strains of E. histolytica (strain A and strain B) at pH 3.00-8.00 with McILvaine buffer, EPM was found to ba negative, which means that under this condition, the amoeba cell surface carries a negative charge. The higher the pH, the greater negative electrophortic mobility, and the more the appearance percent of pseudopodia, there was significant correlation between these phenomena. These results suggest a relationship between movement of amoeba pseudopodia and variations in surface membrane charges.更多还原
