Description

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].

In Vitro

Polyethylenimine branched (ranged PEI/DNA ratio, 24 h) reaches maximal transfection efficiency at 9-13.5 equivalents of PEI nitrogen per DNA phosphate and does not affect cell metabolism in 3T3 cells. [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.
