和质粒的转染试剂。而上述DharmaFECT 1,2,3和4则仅是针对siRNA单独转染的优化产品。虽然共转染siRNA和质粒进行报告基因系统研究越来越普遍,但对应的能够高效共转染siRNA和质粒的转染试剂则很匮乏;大部分的研究者依然运用传统的质粒转染试剂进行siRNA转染或者siRNA和质粒的共同转染,但是这些试剂没有经过转染条件的优化,往往对细胞活力产生很大的毒副作用。基于此,Dharmacon公司推出的具有在保持细胞高活力的情况下高效共转染siRNA和质粒的DharmaFECT Duo转染试剂。

Figure. DharmaFECT Duo
achieves optimal co-transfection results - effectiv plasmid
delivery (black bars) and target mRNA knockdown (blue bars) when
compared to other lipid reagents. The psiCHECK 2 Vector (Promega;
100 ng/well) and siRNA targeting renilla luciferase (100 nM) were
complexed with a range of transfection reagent volumes (0.05 - 0.6
μL/well) to determine optimal co-transfection conditions (shown).
Firefl y Luciferase expression was assessed at 48h using the
Dual-Glo™ Luciferase Assay System (Promega). Cell viability was
assessed using the alamarBlue® Assay (Biosource International).
siRNA-induced Renilla luciferase knockdown (blue bars) was assessed
by branched DNA assay (Panomics).
