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].

體外研究
(In Vitro)

Polyethylenimine branched (波動的 PEI/DNA 比率, 24 h) 在 9-13.5 PEI 氮當(dāng)量 / DNA 磷酸基的比率時達(dá)到最大轉(zhuǎn)染效率,并且不影響3T3細(xì)胞的細(xì)胞代謝[1]。

體內(nèi)研究
(In Vivo)

Polyethylenimine branched (9 eq. PEI/DNA, 腦室注射, 24 h) 在新生小鼠的腦提取物中顯示出高熒光素酶活性[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.
