Description Hexadimethrine bromide (Polybrene) is a cationic polymer that can be used in retroviral and lentiviral infections to improve gene transfer efficiency.
In vitro 方法:人间充质干细胞 hMSCs 用 Hexadimethrine bromide (1-8 µg/mL) 处理 6-24 h,使用 CyQUANT assay 检测细胞数量。结果:在标准培养条件下,21 天后细胞数量增加了 5 倍以上。使用通常用于慢病毒转导的聚布伦处理 (8 µg/mL,24 h),hMSCs 的数量在同一时间段内仅增加了一倍。[1]方法:BHK 和 208F 细胞用 Hexadimethrine bromide (5-20 µg/mL) 和 serum (10%-30%) 处理,检测荧光素酶活性。结果:在没有血清的情况下,BHK 细胞对 Hexadimethrine bromide 的存在作出反应,在低 (4 µg/mL) 浓度下,脂肪感染介导的基因转移效率最初略有增加,随后随着含量增加,效率稳步下降。在208F 细胞,在没有血清的情况下脂质转染效率较低且没有变化,而在有血清的条件下脂质转染随着 Hexadimethrine bromide 浓度的增加而更有效。[2]
