| Phusion DNA Polymerase 5x Buffer (with MgSO4)
| 10 µl
| 1x
|
| dNTP 10mM each
| 1µl
| 200µM each
|
| upstream primer
| 5-50pmol (from 100pmol/µl e.g. 2,5µl)
| 0,1- 1 µM
|
| downstream primer
| 5-50pmol (from 100pmol/µl e.g. 2,5µl)
| 0,1- 1 µM
|
| DNA Template
| variable (dependent on DNA conc.)
| <0,5µg/50µl (e.g. 0,3)
|
| Phusion DNA Polymerase (3u/µl)
| 0,5µl
| ~1,25u/50µl
|
| nuclease free water to final volume of
| 50 µl
