Final Concentrations:
For a 2 mL stock (equivalent to 20 100uL 5X isothermal buffers)
Swivel for 30 minutes in a orbital oscillator for PEG to dissolve fully
Alicuot into 100uL stocks
Store at -80°C
1.33X Gibson Assembly Master Mix
- 100uL 5X Gibson Assembly Isothermal Buffer
- 6.25uL Phusion Polymerase 2 U/uL (cat N° F-350S) from Thermo Scientific
- 2uL Epicentre T5 Exonuclease 1U/uL (cat N° T5E4111K) from Illumina
- 50uL Taq DNA Ligase 2000 U/uL (cat N° M208S) from NEB
For a 375ul 1.33X Gibson Assembly Master Mix
It is important to dilute the T5 Exonuclease stock from 10U/uL to 1U/ul to measure the volume correctly
