| 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]. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. |
| In Vivo |
Polyethylenimine branched (9 eq. PEI/DNA, ICV, 24 h) exerts high luciferase activity in the brain extracts of new born mice[1]. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. |

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.
