Key Performance Data


Achieve robust performance with low-input amounts

Many applications are limited in the available amount of input RNA, which can impact assay performance. StellarScript generates high-quality cDNA across a wide range of RNA input amounts, delivering sensitive performance with very little RNA template.


Improve specificity with a thermostable RT

StellarScript provides enhanced thermostability in comparison to wild-type M-MLV RT and performs equivalent-to-better in comparison to other commercially available M-MLV RT variants with respect to both cDNA yield and lengths generated at elevated temperatures. This improves performance with RNAs that have high degrees of secondary structure, including viral RNA and those that are GC-rich.

For further enhanced thermostability, see StellarScript HT and StellarScript HT+.
