Materials
- primers
- plasmid
- dexynucleoside triphosphate mixture (dNTPs)
Equipment
PCR tubes temperature cycler
Parameters
- for DNA vectors (plasmids) of less than 10 kbases)
- The primers must each be at 100-200 ng/μL
- 100-250 μM of each dNTPs
- denaturing temperature is 95 °C
- extension temperature is 72 °C (extension time 1 min per kb)
- 25-30 cycles
- enzyme concentration is 2.5 units of enzyme/ 50 μL of reaction for vector targets up to 19 kb and must be the last component added to PCR mixture (ie after dNTPS) to prevent degradation of the primers.
Protocol
- prepare the reaction mixture of 50 μL
- add the components in order
