In vivo PolyMag™ Transfection Reagent has been designed for in vivo targeted transfection of various types of nucleic acids such as DNA, RNA, oligonucleotides using magnetic nanoparticles coated with specific polymers.  

DNA complexes can be easily administrated through various injection routes such as systemic administration (intravenous, intra-artery) or local administration (intratumoral, intracerebroventricular).

In vivo Magnetofection™ main advantages in comparison to other procedures:

Increased transfection efficiency

Targeted process (magnetically-driven)

Reduction of the systemic dissemination of vectors during injection

Reduction of the vector doses

Work under non permissive conditions (hypothermia, physiological flow conditions)

Penetration of the vector into tissues

Minimized toxicity

Universal – suitable for all nucleic acids

艾美捷IN VIVO POLYMAG 500 轉(zhuǎn)染試劑#IV-PN30500設(shè)計(jì)用于使用涂有特定聚合物的磁性納米顆粒對(duì)各種類型的核酸（如DNA、RNA、寡核苷酸）進(jìn)行體內(nèi)靶向轉(zhuǎn)染。

DNA復(fù)合物可以通過各種注射途徑輕松給藥，例如全身給藥（靜脈內(nèi)，動(dòng)脈內(nèi)）或局部給藥（腫瘤內(nèi)，腦室內(nèi)）。

IN VIVO POLYMAG 500 轉(zhuǎn)染試劑的結(jié)果示例：
