Product description

2× Medino® HotStart PCR Master Mix (With Dye) is a ready-to-use PCR premixed solution containing Medino® HotStart Taq DNA Polymerase, dNTP and optimized buffer system, amplified only by adding primers and templates, which greatly simplifies the experimental operation steps and improves the high-throughput operation and the reproducibility of the experimental results.Medino® HotStart Taq DNA Polymerase is a hybrid product of  Medino® Taq, antibody and Medino® Taq DNA Polymerase. Medino® Taq, the antibody has high affinity with Medino® Taq DNA Polymerase, 50℃ for 30 min, can still close the activity of Medino® Taq DNA Polymerase.Medino® HotStart Taq DNA Polymerase was completely inactivated by heating 30 sec at a predenaturing temperature, releasing DNA polymerase activity. Use of this heat-initiated taq enzyme can effectively inhibit amplification due to non-specific annealing of the primers. The electrophoresis buffer and dye have been added to the premix solution, allowing the PCR product to direct electrophoresis, and the presence of the dye does not interfere with the amplification efficiency. The PCR product has a 3 ′-dA protruding end and can be easily cloned into the T vector.

  1. Annealing temperature and time: 50 – 60℃ is recommended for the temperature. Too low annealing temperature causes non-specific amplification. Primers were designed with reference to fluorescence quantitative primer standards. The recommended annealing time is set to 30 sec, which can be adjusted within 10 – 30 sec. Too long an annealing time may cause the dispersion of the amplification product on the glue. Can also Set up a temperature gradient to explore the optimal temperature and time of primer annealing as needed.
  2. Extended temperature and time: 72℃ of temperature is recommended. 30 sec/kb is recommended.
  3. Amplification product: Please place the PCR amplification product at -20℃ for storage to prevent DNA degradation.
