McClean: Takara PrimeStar PCR
Takara PrimeSTAR HS DNA Polymerase is a high fidelity PCR enzyme. Use this enzyme and protocol for amplifying PCR products for transformation, cloning, etc (basically any application where you want high fidelity.) Don't use this for things like colony PCR where you don't care if the product has mutations (use the cheap stuff for colony PCR!)
- 5X Takara Primestar Buffer
- DNTPS (2.5mM each)
- Takara Primestar Polymerase
These reagents (buffer, DNTPs, and polymerase) are supplied in kit R010A or R010B (which we currently order through Fisher)
- Primer 1 (10μM)
- Primer 2 (10μM)
- Plasmid DNA (20ng/μl concentration) (or other DNA source)
- Sterile Water
For each 50μL reaction the reaction mix is as follows:
- 5X Takara Primestar Buffer 10μl
- DNTPS (2.5mM each) 4μl
- Primer 1 (10μM) 1μl
- Primer 2 (10μM) 1μl
- Plasmid DNA (20ng/μl concentration) 1μl
- Takara Primestar Polymerase 0.5μl
- Sterile Water 32.5μl
Run PCR Program (labeled takarapcr on thermocycler) 94.0°C for 2 min 98.0°C for 10 sec 53.0°C for 15sec Repeat 30 times 72.0°C for 2min 30sec 72.0°C for 1min 4°C forever
Adjust the extension time according to the expected length of your product (~1 min per kb).

- Megan N McClean 17:48, 29 June 2012 (EDT) As with all PCR reactions, it usually makes sense to make up a master mix (polymerase, DNTPs, and buffer) and then add primers and DNA individually, rather than trying to pipette minute quantities into each individual PCR tube. Use your own good judgement (or add something to this protocol to clarify the master mix principle for other users!)

or instead, discuss this protocol.
