- | ===Bioscaffold Tests===
| |
- |
| |
- | *The entire construct AraC-RBS-FhuA-Bioscaffold-GFP-Terminator was inserted in a pSB2K3 plasmid. pSB2k3 has no restriction enzyme recognition sequences for the Bioscaffold specific enzymes.
| |
- |
| |
- | *Different liquid cultures carrying the entire construct were harvested by centrifugation and DNA was miniprepped.
| |
- |
| |
- |
| |
- | *To test for mutation success for GFP illegal Bioscaffold site, the DNA was tested with Single Digest (XbaI), Single Digest (BpuEI)and Double Digest. As a control premutated DNA was also digested. Incubations were for 60min/37oC.
| |
- |
| |
- | *Successful mutants were identified. Also prolonged incubation leads to BpuEI having star activity. As a result we decided to incubate for 45min. (Bioscaffold enzymes are time-saver qualified and can also be used for 5min incubation).
| |
- |
| |
- | *The Bioscaffold was tested by following its application instructions:
| |
- | Step1: Restrict DNA with BseRI to remove stop codons and DNA scar.
| |
- | Step2: Ligate to convert the remaining stop codon into tyrosine aminoacid (From TA to TAC).
| |
- | Step3: Restrict Digest with BpuEI to collapse bioscaffold.
| |
- | Step4: Ligate to obtain a seemingly scarless fusion.
| |
- |
| |
- | All incubations were for 60min/37oC. After each step, the relevant enzymes were inactivated and DNA purification was implemented.
| |
- |
| |
- | Aliquots from each step were kept and run on an agarose gel to assess Bioscaffold viability.
| |
- |
| |
- | *Transformations with XL-1 Blue cells from each restriction-ligation pair and subsequent restreak and liquid cultures were made. Cells were harvested by centrifugation and DNA plasmid obtained by minipreps.
| |
- |
| |
- | *Aliquots from each step were assessed by BpuEI single digest, BseRI single digest and Double Digest. Preliminary results show bioscaffold to be successful.
| |
- |
| |
- | *Samples were sent for sequencing to confirm if Bioscaffold application was successful.
