Description_x000D_ General description_x000D_ JumpStart™ Taq ReadyMix™ is a ready-to-use 2X master mix that contains JumpStart™ Taq DNA polymerase, 99% pure dNTPs, reaction buffer and JumpStart™ Taq antibody. It combines the performance enhancements of our JumpStart™ Taq Antibody for hot start PCR with the convenience of an easy-to-use reaction mixture. Since it has no added dyes, this is the ideal solution for performing high-throughput, quantitative PCR methods that rely on a fluorescent probe. The Taq DNA polymerase is an antibody-inactivated hot-start enzyme. Once the reaction temperature reaches 70°C, the DNA polymerase-antibody complex dissociates and Taq DNA polymerase activity is restored. This antibody-enzyme complex allows for easy and convenient set-up with less contamination risk than manual hot-start techniques._x000D_ Application_x000D_ JumpStart™ Taq ReadyMix™ for Quantitative PCR has been used:_x000D_ • for quantitative polymerase chain reaction (qPCR) amplification of HIV-1 RNA that is reverse transcribed and DNA using probes_x000D_ • in a 2-step RT-qPCR assay for the quantification of reverse transcribed RNA in a study to monitor the activity of licorice in Treg cell differentiation and function_x000D_ • as a component of the reaction mixture for the detection and amplification of Salmonella sp. and internal amplification control (IAC) pUC 19 plasmid DNA_x000D_ • as a component of the reaction mixture for the detection of Clostridium difficile by quantitative polymerase chain reaction (qPCR)_x000D_ Features and Benefits_x000D_ • Ultimate Convenience. ReadyMixes contain all components necessary for QPCR, simply add fluorescent detection chemistry, primers, and template_x000D_ • Greater Specificity & Increased Target Yield. JumpStart Taq prevents non-specific amplification and increased target yield_x000D_ • Maximum Flexibility. Suitable for use with a variety of detection chemistries including molecular probes and double-stranded binding dyes such as SYBR Green I_x000D_ Packaging_x000D_ Sigma′s Reference Dye for Quantitative PCR is included separately with this ReadyMix for normalization of the reaction data. The dye has a maximum excitation of 586 nm, and a maximum emission of 605 nm. The instrument settings for ROX reference dye are satisfactory for the measurement of the Reference Dye for Quantitative PCR. A tube of 25 mM MgCl2 is also provided for easy optimization of the qPCR reaction._x000D_ Default reaction volume is 50 μL_x000D_ 20RXN is packaged as 1 X 500 μL_x000D_ 100RXN is packaged as 1 X 2.5 mL_x000D_ 400RXN is packaged as 1 X 10 mL_x000D_ Other Notes_x000D_ JumpStart Taq ReadyMix for Quantitative PCR combines the advantages of a hot start enzyme with a ready-to-use mix for high throughput, quantitative PCR (qPCR). It is formulated without a detection chemistry making it suitable for use with a variety of formats including dual-labeled probes, molecular beacons, or double stranded binding dyes such as SYBR Green I._x000D_ Principle_x000D_ The ReadyMix contains JumpStart Taq DNA Polymerase, 99% pure deoxynucleotides, and buffer in an optimized 2× concentrate. To prepare a reaction, 25 μL of the ReadyMix is added to primers, template, detection chemistry, and water for a total reaction volume of 50 μL. Set up can be performed at room temperature since the JumpStart Taq antibody renders the Taq DNA polymerase inactive. During the first denaturation cycle, the antibody dissociates from the enzyme and full activity is restored. No special preparations or protocol changes are required._x000D_ Unit Definition_x000D_ One unit incorporates 10 nmol of total dNTPs into acid-precipitable DNA in 30 min. at 74 °C._x000D_ Legal Information_x000D_ A license to perform the patented 5′ Nuclease Process for research is obtained by the purchase of (i) both Authorized 5′ Nuclease Core Kit and Licensed Probe, (ii) a Licensed 5′ Nuclease Kit, or (iii) license rights from Applied Biosystems._x000D_ This product is an Authorized 5′ Nuclease Core Kit.
