Gene Assembly using the NheI and PstI sites
- Start with first 23 coding nucleotides of gene, eg. 5'-atgcgtaaaggagaagaacttt...-3'
- Replace the atg start codon with the XbaI site: 5'-TCTAGA-3', eg. 5'-TCTAGAcgtaaaggagaagaacttt-3'
- Add 6-8 random nucleotides to the 5' end of the primer, eg. 5'-cgggcTCTAGAcgtaaaggagaagaacttt-3'
- Tweak the 3' end of the primer (add /remove nucleotides) so that the annealing temperature is close to that of VR
- Amplify your gene using the designed forward oligo and VR
- PCR purify the PCR product
- To ensure that the proper size fragment was amplified 5uL of PCR reaction can be run on an agarose gel
- Digest PCR product with XbaI and PstI
- PCR purify
- Digest Vector with NheI and PstI
- PCR purify
- Mix insert and vector in 3:1 ratio and ligate
- Transform into competent cells
- Screen cells for correct insert using VF2 and VR
