2x 1-Step RT-qPCR Mastermix (No ROX)

Description

Kit Features

  • The kit is designed for singleplex RT-PCR with SYBR Green dye.
  • For the reverse transcription step, this kit uses a highly efficient Thermophilic Reverse Transcriptase, 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 DNA polymerase for PCR with SYBR Green dye.
  • 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 ROX, Low ROX or High ROX concentrations for your choice. 

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 weak.

Setup Reaction and Thermocycling

  1. Thaw 1-Step 2X RT-PCR Master Mix and other reaction components at room temperature, mix each component, centrifuge and then place on ice.
  2. Determine the total volume for the number of reactions, add 5-10% extra volume, and prepare assay mix of all components except RNA template. Mix the assay mix, centrifuge and then place on ice.
  3. Aliquot the assay mix into PCR tubes or plate.
  4. Add RNA template to PCR tubes or plate.
  5. Seal tubes with flat, optically transparent caps or seal plates with optically transparent film.
  6. Mix and then briefly centrifuge the tubes or plate.
  7. Program PCR instrument with indicated thermo-cycling protocol.
  8. Load PCR tubes or plate and start to run.
  9. Perform data analysis according to the PCR instrument instructions.

Primersa Variable Variable Each 150-900nM
RNA Templatesb Variable Variable As low as single digit copies of target RNA to ≤1μg total RNA
H2O To 20μL To 10μL

Note:

  • Each primer’s Tm should be designed ≥60°C, preferably between 62°C to 65°C, using primer3 software for high efficiency and specificity.

  •  

    RNA templates should be extracted by a qualified silica-based kit and eluted with low EDTA TE buffer (10mM Tris-HCl, 0.1mM EDTA, pH 8.0-8.3).

Notes:

  • The three-step thermocycling protocol in Table 3 increases overall polymerase activity by 50%, a more effective protocol than Table 2.
  • The primer concentration used in Tables 2 and 3 is typically 0.15-0.2uM.
