Protocol
To complete the ligation reaction it is necessary that the oligo on the 3' end of the amplicon have a phosphate group on its 5' end. This requires a T4 Polynucleotide Kinase reaction (or ordering an oligo with a 5' phosphate). After the addition of the 5' phosphate I will incubate the oligos together in equal molar ratios to and add ligase to perform the ligation reaction.
- Prep
- Resuspend each amplicon to 100 uM according to table
- Phosphorylation
- In a 0.2 mL tube, add ingredients according to table
- Incubate at 37C for 30 min
- Ligation
- Set up 2 reactions with the following reagents
- Add amplicons according to following table (DO NOT ADD LIGASE YET)
- Heat reaction to 95C for 5 min
- Lower temp to 55C
- Add 1 uL Amp Ligase to each reaction without removing from thermocycler; swirl with pipette tip 5 times to mix
- Incubate at 35C for 2 hours
- Purify with DNA column; elute with 30 uL EB
