- Incubate at 37°C/ 10 min.
- Heat inactivate at 75°C/ 2 min.
- [final] = 200 ng/μL / 15 μL = ~13 ng/μL
Ligation
- Use 20 ng of vector for each ligation = 1.5 μL pSB1A3
- Use 1x moles of H2B insert, relative to vector: 1xμL H2B insert = 410 bp H2B / 2000 bp pSB1A3 * 20 ng pSB1A3 / 60 ng/μL H2B = at least 0.07 μL H2B
- Use 1x moles of LOV insert, relative to vector: 1xμL LOV insert = 461 bp LOV / 2000 bp pSB1A3 * 20 ng pSB1A3 / 62 ng/μL LOV = at least 0.07 μL LOV
- Since the calulated amounts are so small and a volume of 5 μL is needed to add to the Gibson assembly mix, each value was multiplied by 2 and rounded for simplicity
