This product is the master mix for QPCR by fluorescence detection based on Taq DNA polymerase. Product generated with Toyobo’s ReverTra Ace -α- cDNA synthesis kit can be used directly in probe assays and intercalator assays just by dilution. It contains BSA, and is suitable for glass capillary systems such as LightCycler. In addition, a passive reference dye is also included making it suitable for use with ABI PRISM 7700 etc. We have confirmed that passive reference does not affect non-utilizing systems such as LightCycler. This master mix contains anti-Taq high anti-Taq monoclonal antibody, so polymerase activity is inhibited at room temperature prior to PCR allowing Hot Start PCR. This reduces extra bands, resulting in high specificity PCR. Realtime PCR Master Mix is a double-concentrated reaction mix containing Hot Start Taq DNA polymerase, and the reagents and passive reference, etc. required to perform PCR. It can be made suitable for probe assays including TaqMan Assay and Hybridization Probe Assay with the preparation of separate primers and probes. SYBR Green Realtime PCR Master Mix is a solution containing Realtime PCR Master Mix and SYBR Green I, and can be made suitable for intercalator assays with the preparation of a separate primer.
1. Intercalator Assay with SYBR Green Realtime PCR Master Mix1st strand cDNA synthesis was performed with HeLa total RNA (100 ng) as the template, using ReverTra Ace -α- (Code No. FSK-101) and random primer, and then samples prepared using a fivefold dilution series starting at ten-fold dilution (1-7). PCR (amplification area: 295 bp) was performed with β-actin as the target using the sample prepared in the above procedure (the volume of the sample was 1/10 of the PCR reaction mix). PCR was performed using LightCycler, at 95°C for 30 seconds, followed by 40 cycles of 95°C for 0 second, 60°C for 0 second, and 72°C for 30 seconds. As a result, excellent amplification curves were obtained for all concentrations (The non-amplification curve for sterile water is blank).
2. TaqMan Assay with Realtime PCR Master Mix
The same samples obtained from the seven step dilution series in example 1 were used to perform TaqMan assay with Pre-Developed TaqMan Assay Reagents β-actin (Applied Biosystems) (The sample was 1/10 the volume of the PCR reaction mix). PCR was performed using ABI PRISM7700, at 95°C for 1 minute, followed by 40 cycles of 95°C for 15 seconds and 60°C for 1 minute. As a result, excellent amplification curves were obtained for all concentrations (The non-amplification curve for sterile water is blank).
