艾美捷科技代理Polysciences品牌。

Polysciences的产品以其高质量和多样性而著称,特别是在聚乙烯亚胺(Polyethylenimine,PEI)转染试剂方面有着显著的优势。Polysciences公司成立于1961年,主要生产和经营生命科学(胶体金、不含甲醛的甲醇等)、病理学和显镜学微球和粒子、磁珠、各种单体和聚体等产品;作为世界上最大最全的多聚化合物供应商,同时也是世界领先的免疫学、组织化学试剂耗材供应商。


Polysciences特色的PEI转染试剂特点包括:

(1)高效性:PEI转染试剂具有高效的瞬转效率和蛋白产量,广泛应用于基因和细胞治疗产品的开发,包括病毒载体和蛋白质工艺开发、临床试验以及商业化生产。

(2)广泛适用性:适用于多种细胞系,如HEK293、CHO、Sf9等,且转染效率高达80%~90%。

(3)升级产品:如PEI MAX 40K,作为第一代PEI 25K的升级产品,其去乙酰化和盐酸盐形式增强了水溶性,提高了转染效率。


产品应用范围包括:

病毒载体开发:可用于生产和优化病毒载体,将基因修饰的病毒载体导入目标细胞内,从而实现基因转染;

重组蛋白表达:可以将编码目标蛋白的基因高效地转入宿主细胞,从而大量表达所需的重组蛋白;

基因编辑技术:如CRISPR-Cas9系统中,PEI转染试剂用于将相关基因编辑组件送入细胞内;

细胞治疗研究:用于提高细胞的治疗效果和生存率,需要将特定的遗传物质传递到细胞内,以改变细胞的行为或增强其治疗效果。
