QuantiTect Reverse Transcriptase is a novel blend of Omniscript and Sensiscript Reverse Transcriptases, which has a high affinity for RNA and is capable of cDNA synthesis from a wide range of RNA amounts (10 pg to 1 µg). In contrast to kits from other suppliers, the QuantiTect Reverse Transcription Kit provides high yields of cDNA template for real-time PCR analysis regardless of where the amplified target region is located on the transcript. Even difficult templates, such as those with high GC-content or complex secondary structure, are successfully reverse transcribed. QuantiTect RT Buffer has also been optimized to be compatible with real-time PCR buffer.
To obtain accurate results in real-time RT-PCR gene expression assays, it is important that only cDNA is amplified and detected. Interference by genomic DNA can be avoided by designing primers or probes that span an exon/exon boundary. However, in cases where this is not possible (e.g., the cDNA is from a single-exon gene), it is essential that the starting RNA sample is free of genomic DNA. Using the QuantiTect Reverse Transcription Kit, contaminating genomic DNA in RNA samples is effectively and rapidly removed with unique gDNA Wipeout Buffer. Time is saved and costs are reduced, since a separate DNase digestion not required, either during or after purification of RNA samples. Also, design of RNA-specific primers or probes is unnecessary.
