Tetro cDNA Synthesis Kit

Tetro™ cDNA Synthesis Kit contains all the necessary components to generate cDNA from an RNA template. The generated cDNA is suitable for PCR with gene-specific primers

Tetro cDNA Synthesis Kit

Highly sensitive -for high-quality, full length cDNA from as little as 10 pg of total RNA

Ultra-stable reverse transcriptase -for long genes and rare transcripts

Simple -one-tube, one-step set-up for highly sensitive PCR

Broad dynamic range -10 pg to 5 μg of RNA

Fig. 1 High sensitivity on mouse total RNA.

A ten-fold serial dilution of RNA (1 μg to 100 pg) was reverse transcribed using Tetro Reverse Transcriptase and oligo (dT)18. The resultant cDNA was then used as template in a PCR using primers for amplification of a 700 bp fragment from mouse b-actin. Lanes 1-5 correspond to PCR product from the serial dilution above, reactions were carried out in duplicate. HyperLadder 50bp (M).

A ten-fold serial dilution of RNA (1 μg to 10 pg) was reverse transcribed using Tetro Reverse Transcriptase and oligo (dT)18. The resultant cDNA was then used as a template in a PCR using primers for amplification of a 470 bp fragment from human GAPDH. Lanes 1-5 correspond to PCR product from the serial dilution above, reactions were carried out in duplicate. HyperLadder 50bp (M).

Product Description

Tetro cDNA Synthesis Kit contains our highly sensitive MMLV reverse transcriptase, oligo (dT)18 and random hexamer primers and all the necessary components to generate high quality cDNA from RNA templates (fig. 1). The first-strand cDNA generated is ideal for PCR (fig. 2) and can be used in a variety of other applications, such as analyses of cellular RNAs, characterization of RNA splice variants and the generation and cloning of cDNA.

Tetro cDNA Synthesis Kit is optimized for RT reactions over a wide range of total RNA concentrations (10 pg-5 μg), such that long and low-abundance cDNAs can be detected by amplification after cDNA synthesis. The kit contains oligo (dT)18 and random hexamer primers. The kit components are fully optimized to generate maximum yields of full-length cDNA.

FAQs:

Tetro cDNA Synthesis Kit

I want to generate cDNA from RNA with high secondary structure. What do I have to consider?
For SensiFAST cDNA Synthesis Kit: The TransAmp Buffer already contains reverse transcriptase enhancers that reduce complex RNA secondary structure. For templates that have a high degree of structure, such as viral RNA and some plant RNA, we suggest using an additional 15 minute 48°C incubation step as mentioned in the manual. For Tetro cDNA Synthesis Kit: For samples with high secondary structure we suggest to denature the RNA template with primers prior to the reaction set-up. Furthermore, it is necessary to optimize the incubation time and temperature. The temperature of the RT step may be raised up to a maximum of 48°C.
What would be the recommended amount of cDNA generated with these kits to use in PCR reactions? What are common recommendations for sample dilution?
The necessary amount of cDNA template for PCR or qPCR reactions may vary from the range of pg up to several hundred ng. It depends among other things on the analyzed target, the used application and sample characteristics. If you do not have empirical values for your assays please use the recommended amounts in the manuals of your PCR or qPCR assays and optimize if necessary.
Is it possible to use gene specific primer for cDNA synthesis with Meridian kits and what are the advantages?
It is not possible for the SensiFAST cDNA Synthesis Kit. Random Hexamer and oligo dT primer are already included in the optimized TransAmp buffer. It is possible to use gene specific primer for the Tetro cDNA Synthesis Kit to generate cDNA for specific target.
What are the differences / recommended applications for the SensiFAST and Tetro cDNA Synthesis kits?
The SensiFAST cDNA Synthesis Kit has been designed for rapid generation and unbiased coverage of cDNA, especially for subsequent quantification with real-time PCR. The optimized 5x TransAmp buffer includes all necessary components for cDNA synthesis, including a unique blend of oligo dT and random hexamer primers and the RiboSafe RNase Inhibitor. The Tetro cDNA Synthesis Kit is the more flexible solution. You selects the desired setup, especially the desired RT primer. The Tetro Kit is optimized to work over a wide range of RNA concentrations and to obtain full length cDNA, which can be used for two-step PCR assays as well. Tetro is the recommended Kit for the generation of cDNA libraries and cloning.
