生物活性

Polyethylenimine (PEI) branched is a organic macromolecule with high cationic-charge-density potential. PEI can ensnare DNA as well as attach to cell membrane, PEI also retains a substantial buffering capacity at virtually any pH. PEI is widely used as transfection reagent[1].

体外研究
(In Vitro)

Polyethylenimine branched (波动的 PEI/DNA 比率, 24 h) 在 9-13.5 PEI 氮当量 / DNA 磷酸基的比率时达到最大转染效率,并且不影响3T3细胞的细胞代谢[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
