The Stemgent microRNA Booster Kit enhances, and simplifies mRNA reprogramming for fast, efficient iPS cell line generation from both normal and patient specific cell lines.The microRNA Booster Kit includes the microRNA Reprogramming Cocktail and B18R Recombinant Protein.
The microRNA-enhanced mRNA Reprogramming method improves upon the first generation mRNA Reprogramming Kit, delivering faster reprogramming kinetics, a streamlined protocol and improved efficacy on hard-to-reprogram or refractory cell types. The microRNA-enhanced method combines Stemgent’s mRNA Reprogramming Kit with the microRNA Booster Kit and the Stemfect™ RNA Transfection Kit to generate expandable primary iPS cell colonies in as little as 8 days. This new method improves kinetics and reduces mRNA dose per transfection resulting in a per well cost reduction of approximately 35% to 45% versus feeder-based mRNA Reprogramming.
