Invitrogen SuperScript III Reverse Transcriptase is a genetically engineered MMLV reverse transcriptase (RT) that was created by introduction of several mutations for reduced RNase H activity, increased half-life, and improved thermal stability. SuperScript III RT offers higher cDNA yields, improved cDNA lengths, improved efficiency on GC-rich target RNAs, and overall better performance than wild-type MMLV and MMLV RNase H-minus enzymes.

SuperScript RTs are the most highly trusted and widely used RTs with over 50,000 citations, reviews, and publications to date.

Note: The latest member of the SuperScript RT family, SuperScript IV Reverse Transcriptase, features enhanced thermostability, processivity, yields, and performance with any RNA samples, including those of suboptimal purity or integrity.
