應用
用于在富含胆固醇的细胞质膜上穿孔（可逆穿孔），使蛋白质（高达100 kDa)和siRNA等分子可以选择性透膜。
链球菌溶血素O(Streptolysin O)是化脓性链球菌(Streptococcus pyogenes)分泌的毒素，是成孔细菌溶细胞素的原型成员。 用于穿透细胞膜，便于细胞摄取大分子或带电分子。 可用于研究大分子运输。 作为潜在抗癌药，可用于研究自杀基因癌症治疗。
透膜允许细胞摄取大分子或带电分子。
生化／生理作用
能穿透动物细胞膜的巯基活化毒素。该蛋白作为单体与膜胆固醇结合，随后聚合成围绕>12 nm孔的大弧形和环形结构。
链球菌溶血素O由分子量为62 kDa的单条多肽链组成。 链球菌溶血素O可结合细胞膜胆固醇，并聚合形成含45-50个单体的环形结构。 环结构插入膜中形成一个可供DNA、RNA、肽和蛋白分子通过的大孔洞（25-30nm）。 硫醇活化。 受大蒜活性成分——大蒜素(Allicin)抑制。
