Invitrogen™ SuperScript™ IV First-Strand Synthesis System with ezDNase™ Enzyme, 50 Reactions
On demandInvitrogen™ SuperScript™ IV First-Strand Synthesis System with ezDNase™ Enzyme, 50 Reactions
The SuperScript IV First-Strand Synthesis System with ezDNase Enzyme for RT-PCR is optimized for synthesis of first-strand cDNA from purified poly(A)+ or total RNA. The kit includes SuperScript IV Reverse Transcriptase (RT), a proprietary MMLV mutant that produces robust and reliable cDNA synthesis in RT reactions, and ezDNase to remove potential genomic DNA contamination. The SuperScript IV synthesis system is significantly improved over the SuperScript III-based system in inhibitor resistance, processivity, and reaction speed, while retaining all the benefits of the previous system, including increased thermostability, highly efficient full-length cDNA synthesis, and reduced RNase activity. The SuperScript IV system is designed to provide reliable, consistent, and fast cDNA synthesis in the presence of inhibitors found in a wide variety of samples that cause other currently available RTs to perform inefficiently.
The SuperScript IV First-Strand Synthesis System contains all components needed for RT reactions, plus an additional control gene and primers, and provides the flexibility to customize the RT set-up to fit the needs of your application. For even better performance, ezDNase for genomic DNA removal is included. The extremely simplified genomic DNA removal step dramatically reduces the time of the entire reverse transcription protocol and reduces possible variation in gene expression due to RNA loss or damage during conventional DNase treatment. The SuperScript IV synthesis system with ezDNase is the top choice for performance and flexibility for RT-PCR applications. We recommend it for all RT-PCR applications, especially when reproducibility and reliability is the primary concern and when inhibitors in the RNA sample may interfere with cDNA synthesis, leading to biases in gene expression studies.
