Intended Use The Master Mix is used for real-time qualitative and quantitative RT-PCR amplifications with SYBR Green dye for extraction-free RNA samples. The master mix is a premixed, 2X concentrated solution that has all the components except for gene-specific primers. Kit Features The master mix contains extra more redundant amounts of the RTase and DNA polymerase, specifically designed to overcome endogenous inhibition in extraction-free RNA samples. For the reverse transcription step, this kit uses a highly efficient Thermophilic Reverse Transcriptase (US patent pending), which is a thermophilic type A polymerase, with optimal temperatures of 60-62°C. The RTase is easily heat-inactivated at ≥90°C for 1min. The RTase efficiently synthesizes a complementary DNA strand on RNA template from a gene-specific primer, ≤1 unit per 20μL of reaction. The RTase reversely-transcribes single digit copies of target RNA molecules consistently. The kit also contains Taq-Fast DNA polymerase which extends more than 300 bases with short cycling program. The concentrations of the primers are variable depending on assay designs and thermocycling protocols (Table 1). The preferable PCR product size is ≤150bp. The kit has three formulations of No ROX, Low ROX or High ROX concentrations for your choice.Kit Contents 2X Master Mix (2x1mL/5x1mL/10mL for 200/500/1000 reactions x 20μL) and an instruction for use. The kit also contains Lysis Buffer (2x10mL/1x50mL/1x100mL). Transportation and Storage The kit can be transported at below 4°C for up to 3 days. The kit should be kept stable in the dark at -20°C for ≤24 months with ≤10 times of freeze-thaw cycles. The kit can be stored at 4°C for a week. Protocol for extraction-free RNA from cultured cells Wash 10,000-20,000 adherent cells in a well or suspension cells in a medium with 1X PBS buffer. Add 50-100ul Lysis Buffer to the well or to the collected cells, and leave for 5min. Break down the cells through either sonicator, or vigorous vortex for 1 min. Heat at 95ºC for 10min and then cool down to 4°C. Up to 4μl of lysed RNA sample can be added to a 20ul final RT-PCR volume.Note: the recovery rate of the extraction-free RNA is heavily affected by how completely the cells are broken down. Setup Reaction and Thermocycling Thaw 1-Step 2X RT-PCR Master Mix and other reaction components at room temperature, mix each component, centrifuge and then place on ice. Set up reactions (Table 1). Seal tubes with flat, optically transparent caps or seal plate with optically transparent film. Mix and then briefly centrifuge the tubes or plate. Program PCR instrument with indicated thermo-cycling protocol. Load PCR tubes or plate and start to run. Perform data analysis according to the PCR instrument instructions. Table 1.
