What is Mastermix in PCR?
A PCR master mix, sometimes known as super mix or ready mix, is a batch mixture of PCR reagents at optimal concentrations that can be prepared and divided among many PCR tubes or 96-well PCR plates. The master mix usually includes DNA polymerase, dNTPs, MgCl2 and buffer.
What does a PCR Master Mix contain?
PCR Master Mix is a premixed, ready-to-use solution containing Taq DNA polymerase, dNTPs, MgCl2 and reaction buffers at optimal concentrations for efficient amplification of DNA templates by PCR.
How do you calculate Master Mix for PCR?
To make mastermix: multiply amount of dNTP per reaction by number of reactions. See Standard PCR Protocol for example of how to make a master mix.
What is the purpose of PCR master mix?
The PCR Master Mix is designed for routine endpoint PCR for DNA amplicons in the range of 0.2–2kb. PCR Master Mix allows you to set up your reactions in less than a minute—just add template and primers. Optimized conditions enable amplification of as few as 2 copies of target template.
How do you perform a PCR procedure?
A standard polymerase chain reaction (PCR) setup consists of four steps:
- Add required reagents or mastermix and template to PCR tubes.
- Mix and centrifuge.
- Amplify per thermo cycler and primer parameters.
- Evaluate amplified DNA by agarose gel electrophoresis followed by ethidium bromide staining.
Why is GoTaq master mix dyed?
GoTaq® Green Master Mix contains two dyes (blue and yellow) that allow monitoring of progress during electrophoresis.
Can you store PCR Master Mix?
Dear Soha, the hot start master mix is already designed to store below -20 C, this freezing temperature and even the room temperature when you need to thaw this master mix for your PCR, the enzyme remains stable as it will only activate at certain temperature during the PCR run.
