biotechrabbit™ Lyo Hot Start PCR Master Mix is a freeze dried version of the well-established liquid equivalent. The stabilized format allows shipment and storage without cooling. The Master Mix is a perfect choice for a fast reaction setup that reduces the time required for calculation and pipetting and eliminates the need for buffer optimization. It is designed for low-background, high-throughput PCR of 0.2–3 kb DNA targets.

The 2x Hot Start PCR Master Mix contains pure biotechrabbit Hot Start Taq DNA Polymerase, extremely high-quality dNTPs and optimized PCR buffer; thus, only template, PCR primers and PCR-grade water are added.

The Hot Start Taq DNA Polymerase is inactive during reaction setup due to the bound antibody, which is quickly released at elevated temperatures, ensuring the enzyme is active only during PCR. There is no need for prolonged heating or denaturation steps. The hot start minimizes primer–dimers and mispriming.

 

Info: Recommended annealing temperature is 2°C above primer Tm (use gradient PCR to optimize the annealing temperature).

Human genomic DNA was amplified using the reconstituted Hot Start PCR Master Mix and specific primers to produce a distinct band.

 

Prevention of PCR contamination

When assembling the amplification reactions, care should be taken to eliminate the possibility of contamination with undesired DNA.

  • Use separate clean areas for preparation of samples and reaction mixtures and for cycling.
  • Wear fresh gloves. Use sterile tubes and pipette tips with aerosol filters for PCR setup.
  • Use only water and reagents that are free of DNA and nucleases.
  • With every PCR setup, perform a contamination control reaction that does not include template DNA.
Standard PCR setup

The standard PCR protocol using biotechrabbit reaction buffer provides excellent results for most applications. Optimization might be necessary for certain conditions, such as the amplification of long targets, high GC or AT content, strong template secondary structures or insufficient template purity. In such cases, optimization of template purification (see biotechrabbit nucleic acid purification kits), primer design and annealing temperature is recommended.

The best conditions for each primer-template can be optimized with the following:

  • Choosing the optimal quantities of template and primers
  • Using a PCR Enhancer (i.e. BR1900201) for low amounts of template, impure or GC-rich templates
  • Optimizing cycling conditions
Basic Protocol
  • The Master Mix is designed to be used without any optimization as it has all necessary reaction components in optimal amounts for successful PCR.
  • Optionally, 5× PCR Enhancer (BR1900201) can be used to increase the yield and to lower the background in more complicated PCR reactions (low amounts of template, impure or GC-rich template).
  • Thaw on ice and mix all reagents well.
  • Keep all reagents and reactions on ice.
  • Pipet the Master Mix into thin-walled 0.2 ml PCR tubes.
  • Add template and primers separately if they are not used in all reactions.
