In Vivo Transfection Reagents:

Although transfection reagents which are usually positively charged vectors expose high gene transfer activity in vitro, systemic administration of such particles is rather restricted. After tail vein injection of different positively charged lipo- and polyplexes into mice, complexes were rapidly cleared from the circulation and mainly accumulated in the lung due to the unspecific binding with extracellular components.

To eliminate the unspecific interaction between cationic nonviral vector with blood components in circulation, we utilized GenJet™ Plus reagent as backbone and cross-linked a shielding peptide (SP) with amine group of neutral lipid of the backbone. The initial testing results showed that administration of shielded GenJet™ Plus did not induce erythrocyte aggregation. Instead systematic injection of shielded GenJet™ Plus led to enhanced systematic circulation with significant improvement of renilla luciferase expression in lung, spleen and liver compared with control GenJet™ Plus without shield peptide.

PepJet™ DNA In Vivo Tranfection Reagent

Description PepJet™ DNA In Vivo Tranfection Reagent is a novel cationic peptide based DNA delivery tool. This 28 amino-acids long peptide is accidentlly identified as a strong vector in delivering DNA in vivo. With help of protein alignment and simulation software, the peptide was synthesized, refined, screened and validated by simulating a virus protein. A shield peptide was also linked to the backbone to prevent In Vivo environment interferences, leading to...
