The influence of serum and DNA quantity on transfection using SuperFect Reagent was examined. COS-7 cells (2 x 104 per well) were seeded in 96-well plates one day prior to transfection. Cells were transfected using 0.1–2.0 µg beta-galactosidase-reporter plasmid and 3 µl SuperFect Reagent per well, in either the presence or absence of serum. Each bar represents the average efficiency from 4 replicates assayed 48 hours after transfection.|Note the highly branched structure of an activated dendrimer in this schematic representation.|A model of the SuperFect-DNA complex shows SuperFect Reagent (purple balls) interacting with DNA (black) to form a ring-like (toroid-like) structure. The upper right section of the illustration shows naked DNA, the lower section shows the interaction between dendrimers and DNA inside the complex, and the upper left section shows the final complete coverage of DNA within the complex.|Expression of green fluorescent protein (GFP) in differentiated PC-12 cells was examined 5 days post-transfection. Cells (104–105)  previously stimulated with 50 ng/ml NGF were plated per 60 mm dish one day prior to transfection. Transient transfections were performed in 2 ml low-serum growth medium (DMEM plus 0.05% FBS) using 3 µg of a GFP-reporter plasmid and 15 µl SuperFect Reagent. (Data kindly provided by K.

SuperFect Reagent gives high transfection efficiency even when mixed with growth medium which can contain serum and antibiotics (see figure "Serum and DNA quantity vs. transfection efficiency"). SuperFect Reagent is suitable for transient and stable transfection of a broad range of cell lines (see figure "Transfection of neuronal PC-12 cells using SuperFect Reagent").



SuperFect Reagent consists of activated-dendrimer molecules with a defined spherical architecture. Branches radiate from a central core and terminate at charged amino groups which can then interact with negatively charged phosphate groups of nucleic acids (see figure "Activated dendrimer"). SuperFect Reagent assembles DNA into compact structures that bind to the cell surface and are taken into the cell by nonspecific endocytosis (see figure "SuperFect–DNA interaction"). The reagent buffers the pH of the endosome, leading to pH inhibition of endosomal nucleases, which ensures stability of SuperFect–DNA complexes. Due to highly controlled chemical synthesis the activated-dendrimer molecules in SuperFect Reagent have a precise size and a defined shape. This ensures consistent transfection-complex formation and reproducible transfection results.


SuperFect Transfection Reagent is provided as a ready-to-use solution. The reagent is simply added to the DNA solution, mixed, and incubated for 5–10 minutes to allow SuperFect–DNA complexes to form. The complexes are mixed with growth medium (which can contain serum and antibiotics) and added directly to the cells. After a 2–3 hour incubation, a medium change is performed and the cells are incubated for expression of the transfected gene. Transfection using SuperFect Reagent requires minimal handling, making it highly suitable for high-throughput screening. SuperFect Reagent provides high transfection efficiencies, excellent reproducibility, and low cytotoxicity in high-throughput transfection, and is available in bulk quantities.
