Product Overview

The Stemfect RNA Transfection Kit is a proprietary mixture of lipid components is specifically designed for in vitro RNA transfection. This kit has been shown to deliver mRNA, siRNA and miRNA. Stemfect RNA Transfection Kit provides greater than or equal to 90% transfection efficiency of mRNA into a range of cell types with greater than 95% viability; these cell types include human embryonic stem (hES) cells, Jurkat cells, human fibroblasts, and HEK293T cells. Stemfect RNA Transfection Kit has been successfully used to deliver RNA to human ES cells, dendritic cells, and retinal pigment epithelial cells. There is no need to serum-starve cells using this kit as the transfection efficiency remains greater than or equal to 90% in the presence of serum.
