ScreenFect GmbH成立于2012年，是一家专注于细胞转染技术创新的德国生物技术公司。ScreenFect®转染试剂是该公司的核心产品，是依托组合化学方法构建独特化学文库，通过高通量细胞筛选平台高效开发的转染试剂。ScreenFect®转染试剂适用于多种核酸分子（包括pDNA、siRNA、mRNA、miRNA）的单转染与共转染，在难转染细胞（如原代细胞、干细胞）中具有优异性能。

▎ScreenFect®转染试剂

● ScreenFect®A是一款通用型转染试剂，适用于pDNA、siRNA、mRNA的递送以及共转染实验，可广泛应用于多种细胞系（如HEK、HeLa、MEF）及部分原代细胞系。高效转染：在96孔板中仅需低于100ng DNA即可实现高转染效率。

● ScreenFect®siRN 是转染小干扰RNA双链体的理想选择，适用于HEK、HeLa、MEF等标准哺乳动物细胞系及多种原代细胞系。

● ScreenFect®mRNA是专为mRNA转染优化的高效试剂。

● ScreenFect®A-plus是一款多功能增强型转染试剂，适用于pDNA、siRNA、mRNA的转染及共转染实验，在几乎所有细胞系（包括难转染细胞）中均能实现高效转染。

ScreenFect®转染试剂具有以下特点：

● 低细胞毒性：显著降低对细胞活性的影响

● 省时一步法：支持细胞铺板与转染同步操作（即用型方案）

● 快速优化：针对新用户/新细胞系提供简易优化流程

● 血清兼容性：无需更换培养基，可直接在含血清环境下使用

● 无动物源成分：杜绝动物源性物质污染风险

● 高通量适用：完美适配大规模筛选实验需求
