Automation is used for many applications to reduce variation caused by manual handling and to obtain reproducible results in high-throughput assays. High-throughput applications, such as knockdown studies or target screenings, often include cell transfection.
Small inhibitory RNAs (siRNAs) have become the focus of interest in many laboratories. For the first time, these molecules offer an easy way to knock down the expression of selected genes in mammalian cells without having to resort to classical gene knockout techniques.
You are not alone designing successful CRISPR, RNAi, and ORF experiments. Sigma-Aldrich was the first company to commercially offer lentivirus versions of targeted genome modification technologies and has the expertise and commitment to support new generations of scientists.
Our Universal Transfection Reagent is a unique formulation of a proprietary polymer blend used for transient and stable transfection of nucleic acids into various eukaryotic cell lines and hard-to-transfect primary cells. This is a fast and easy protocol is compatible with serum, serum-free medium and antibiotics.
Cell preparation for transfection Plate cells approx. 24 hours before transfection making sure cells are at optimal concentration (70 – 90 % confluency).
Applications, principles, and methods for in vitro mammalian cell culture including links to articles, protocols, and videos for proper aseptic technique, passaging and subculturing, and culture media considerations.
