일반 설명
FastStart TaqMan® Probe Master is a ready-to-use hot start reaction mix without ROX for quantitative polymerase chain reaction (qPCR) and reverse transcription (RT)-qPCR on real-time PCR systems other than the LightCycler® instruments. It is a 2x concentrated master mix that contains all the reagents (except primers, probe, and template). This master mix simplifies the preparation of reactions for DNA detection and analysis. It allows very sensitive detection and quantification of defined DNA sequences.
Hot start protocols have been also been shown to significantly improve the specificity and yield of PCR. Heat-labile blocking groups on some of the amino acid residues of FastStart Taq DNA Polymerase make the modified enzyme inactive at room temperature. Therefore, there is no elongation during the period when primers can non-specifically bind. The FastStart Taq DNA Polymerase is activated by removing the blocking groups at a high temperature (i.e., a pre-incubation step at +95°C).
This FastStart TaqMan® Probe Master can be used for the amplification and detection of any DNA or cDNA target, including those that are GC- or AT-rich. However, you would need to adapt your detection protocol to the reaction conditions of the particular real-time PCR instrument used and design a specific hydrolysis probe and PCR primers for each target.
Combination of this master mix with our Transcriptor First Strand cDNA Synthesis Kit achieves excellent results in two-step qRT-PCR.

Heat-labile blocking groups on some of the amino acid residues of FastStart Taq DNA Polymerase make the modified enzyme inactive at room temperature. Therefore, there is no elongation during the period when primers can nonspecifically bind.

기타 정보
qPCR targets
In principle, the FastStart TaqMan® Probe Master can be used for the amplification and detection of any DNA or cDNA target, including those that are GC- or AT-rich. However, for each target, you would need:
See the Operator′s Manual of your real-time PCR instrument for general recommendations.
Two forms available
The master mix is available in two forms – one that contains the ROX reference dye and one without ROX.
Preventing carryover contamination
This master contains dUTP, which will be incorporated into PCR products to help prevent false positives resulting from carryover contamination. In subsequent PCRs, you can add Uracil-DNA Glycosylase to degrade any uracil-containing carryover contaminants (amplification products from previous PCRs).
qRT-PCR
Combine this master mix with our Transcriptor First Strand cDNA Synthesis Kit for two-step qRT-PCR. This kit gives excellent results and works efficiently with all real-time PCR instruments.

A PCR master mix is a batch of PCR or RT-PCR reagents that can be divided among many PCR reaction tubes. It usually includes DNA polymerase, dNTPs, MgCl2 and buffer. Make your own master mix or choose a commercial one.
The purpose of Hot Start PCR is to inhibit the PCR reaction in order to reduce nonspecific amplification, prevent the formation of primer dimers, and increase product yields.

Polymerase chain reaction (PCR) is a technique for amplifying nucleic acid molecules and is commonly used in many applications, including RT-PCR, hot start PCR, end point PCR and more.
RT-qPCR, or quantitative reverse transcription PCR, combines the effects of reverse transcription and quantitative PCR or real-time PCR to amplify and detect specific targets. RT-qPCR has a variety of applications including quantifying gene expression levels, validating RNA interference (RNAi), and detecting pathogens such as viruses.
