pEF1α-IRES is a bicistronic mammalian expression vector that allows simultaneous, constitutive expression of two genes of interest from the same mRNA transcript, even after stable integration of the vector into the host cell genome. Stable, constitutive expression of the bicistronic transcript is driven by the human elongation factor 1 alpha (EF1α) promoter, allowing the investigation of a variety of cellular processes (such as differentiation in primary or stem cells) without the transgene silencing associated with CMV promoters.

Xfect is a transfection reagent that creates biodegradable nanoparticles that permit superior transfection efficiency of plasmid DNA into mammalian cells. Transfections can be carried out entirely in the presence of serum.

NucleoSpin Plasmid Transfection-grade is a fast miniprep kit that uses a new technology developed by Macherey-Nagel to reduce the level of endotoxins co-purified during plasmid preparations from bacterial lysates. Since endotoxins interfere with eukaryotic cell survival, endotoxin reduction is essential prior to cell transfection.
