Description
The ExcelRT™ One-Step RT-qPCR kit (TaqMan, ROX) is designed for reverse transcription and quantitative real-time analysis of a specific target RNA by one-step reaction. The ExcelRT™ One-Step RT-qPCR kit (TaqMan, ROX), consisting of One-Step RT Enzyme Mix and 2X One-Step qPCR Master Mix, is a convenient kit designed for highly efficient cDNA synthesis and highly specific real-time PCR in a single tube. The One-Step RT Enzyme Mix contains a thermostable ExcelRT™ Reverse Transcriptase and a RNAok™ RNase inhibitor. Consequently, One-Step RT Enzyme Mix can reverse transcribe RNA to cDNA at a wide temperature range from 42 to 60°C and active against RNase A, RNase B and RNase C. By containing specialized hot-start Taq DNA polymerase, which greatly reduce primer-dimer formation and can be activated within 2 minutes, the 2X One-Step qPCR Master Mix features high specificity and is suitable for fast cycle program. This master mix includes ROX reference dye for normalization of each RT-qPCR assay.

Reverse transcription at wide template range
ExcelRT™ One-Step RT-qPCR Kit can quantitative analyze target RNA from a wide range of RNA template input. The amplification plot of one-step RT-qPCR with total RNA templates ranging from 1 pg to 1 ng in quantity, analyzed by using RQ2110 ExcelRT™ One-Step RT-qPCR Kit (TaqMan, ROX) for RT-qPCR amplification.
Reverse transcription at wide temperature range (42-60°C)
ExcelRT™ One-Step RT-qPCR Kit can quantitative analyze target RNA at a wide temperature range (42-60°C). The amplification plot of one-step RT-qPCR with reverse transcription at temperature range from 42 to 60°C, analyzed by using RQ2110 ExcelRT™ One-Step RT-qPCR Kit (A) or kit from brand N (B) for RT-qPCR amplification. The overlapped amplification curves display that ExcelRT™ One-Step RT-qPCR Kit preforms successfully cDNA synthesis at wide temperature range.

Recommended primer design
Amplicon size: 80-150 bp
Tm value: around 60°C (calculated with Primer3 software)
Primer length: 17-25 mer
Sequence:
‒ 45-55% of GC content isrecommended.
‒ Avoid regional high GC or ATcontent
‒ Avoid palindrome sequence
‒ Sequence with G or C at the 3" end is recommended.
Specificityof primers should be confirmed through a BLAST search.
Recommended probe design
Tm value: 6-10°C higher than primers
Probe length: 20-30 mer
Sequence:
‒ 35-65% of GC content is recommended.
‒ Avoid regional high GC or AT content
‒ Select the strand contains more C’s than G’s
‒ Avoid palindrome sequence
‒ Avoid a G at the 5" end to prevent quenching of the 5’fluorophore.
Specificityof probe should be confirmed through a BLAST search.
