Product Introduction：PEI 25K is a powerful, trusted, and cost-effective transient transfection reagent. In HEK293 and CHO expression systems, PEI offers consistently high gene expression on a wide scale (96 well plates up to 100 L bioreactors). Each year, more researchers and companies turn to Polysciences PEI to gain a critical edge in their work. Relative to most other options, using PEI to prepare transfection reagents in-house can offer as much as a 40% reduction in total transfection costs.

线性化聚乙烯亚胺pei 25,000,一种高电荷阳离子聚合物,非常容易结合于高电荷阴离子基质。工业应用上,线性化pei可改善负电荷染料的物理外观,以调整染料的化学特性和增强染料与固相基质的黏附能力,常用作黏附增强剂,作用司多聚赖氨酸(polv-lvsine):科研应用上,线性化pei能与dna或其他负电荷生物大分子简单结合,正是这一特性,使得成为一种非常行之有效的载体运输介质(vector carrier),即转染试剂
