QuantiTect Probe RT-PCR Kit

 QuantiTect Probe RT-PCR Kit


The QuantiTect Probe RT-PCR Kit has a unique RT-PCR buffer that promotes highly specific annealing of primers and probes to the PCR template. It contains HotStarTaq DNA Polymerase, which provides the most stringent hot start compared with other polymerases (see figure Highly specific amplification).

HotStarTaq DNA Polymerase and the unique composition of the RT-PCR buffer enable the QuantiTect Probe RT-PCR Kit to provide sensitive quantification of low-copy RNA targets, as well as accurate quantification over a wide linear range (see figure High sensitivity and efficiency, and wide dynamic range). Performing reverse transcription and PCR sequentially in the same tube does not impair sensitivity, as demonstrated by CT values that are comparable to those achieved in real-time two-step RT-PCR (see figures One-step RT-PCR with comparable performance to two-step RT-PCR — A and One-step RT-PCR with comparable performance to two-step RT-PCR — B, and table).

QuantiTect Probe RT-PCR Kits contain an optimized, ready-to-use master mix for highly specific and sensitive real-time quantification of RNA targets using sequence-specific probes. The kits are designed for use with all types of sequence-specific probes, including hydrolysis probes (e.g., TaqMan and other dual-labeled probes), FRET probes, and Molecular Beacons. QuantiTect Probe RT-PCR Kits contain a unique PCR buffer that contains a balanced combination of K+ and NH4+ ions, which promote specific primer annealing, enabling high PCR specificity and sensitivity (see figure Specific primer annealing). In addition, an optimized mix of reverse transcriptases enables cDNA synthesis from a wide range of RNA template amounts, while HotStarTaq DNA Polymerase provides a stringent hot start, preventing the formation of nonspecific products.

QuantiTect Probe RT-PCR Master Mix also contains dUTP, enabling pretreatment with uracil-N-glycosylase (UNG) prior to starting PCR, which ensures that any contaminating PCR products do not affect subsequent PCR reactions.
