PROJECT LAB BOOK
Here you will find a day-by-day account of our triumphs and failures.
A day-by-day progress for Agrobacterium Tumefaciens Bacteriophytochrome
20th August 2010
Genomic DNA extraction
- The first primer pair is (AT-BHO-F) with (AT-BHO-R) [this will insert the bacteriophytchrome gene BEFORE the heme oxygenase gene in the operon]
- The second primer pair is (AT-AHO-F) with (AT-AHO-R) [this will insert the bacteriophytochrome gene AFTER the heme oxygenase gene in the operon]
Mastermix: | Amount per sample (ul) |
---|---|
Gibco H2O | 13.75 |
10x Buffer | 2.00 |
Polymerase enzyme | 0.25 |
dNTP | 1.00 |
Fwd primer | 1.00 |
Rvs primer | 1.00 |
Genomic DNA | 1.00 |
Total | 20.00 |
The PCR program was set up as per the following:
- 94˚C for 2 minutes
- 94˚C for 30 seconds
- 60˚C for 30 seconds
- 72˚C for 2 minutes & 30 seconds
- 72˚C for 10 minutes
- 4˚C to end.
(This was repeated for another 25 cycles)
Experimental Design – Primer combinations and annealing temperatures:
Fwd Primer | Rvs primer | Temp 1 (Degrees Celsius) | Temp 2 (Degrees Celsius) | Temp 3 (Degrees Celsius) | Temp 4 (Degrees Celsius) | Temp 5 (Degrees Celsius) |
---|---|---|---|---|---|---|
(AT-BHO-F) | (AT-BHO-R) | 57.1 | 58.7 | 60.6 | 63.4 | 64.8 |
(AT-AHO-F) | (AT-AHO-R) | 57.1 | 58.7 | 60.6 | 63.4 | 64.8 |
Figure 4. PCR Optimisation (gradient PCR) results
No products were observed. The anticipated product size was between 1.6kb and 3kb. The gel was over run but the only products that were over run were probably primer dimers, which are less than 300bp in size. = FAIL!

10th September 2010
PCR Optimization (repeated)
Mastermix: | Amount per sample (ul) |
---|---|
Gibco H2O | 13.75 |
10x Buffer | 2.00 |
Polymerase enzyme | 0.25 |
dNTP | 1.00 |
Fwd primer | 1.00 |
Rvs primer | 1.00 |
Genomic DNA | 1.00 |
Total | 20.00 |
The first PCR program was set up as per the following:
- 94˚C for 2 minutes
- 94˚C for 30 seconds
- 60˚C for 30 seconds
- 72˚C for 2 minutes & 30 seconds
- 72˚C for 10 minutes
- 4˚C to end.
(This was repeated for another 35 cycles)
The second PCR program was set up as per the following (this was for the amplification of product using the (AT-FWD-RBS) and (AT-AHO-R) primer pair):
- 94˚C for 2 minutes
- 94˚C for 30 seconds
- 40˚C for 30 seconds
- 72˚C for 2 minutes & 30 seconds
- 72˚C for 10 minutes
- 4˚C to end.
- The second PCR program was set up as per the following. There were two parts to this PCR to allow for the (AT-BHO-F) primer to anneal properly after initial annealing of the (AT-BHO-R) primer.
- 94˚C for 2 minutes
- 94˚C for 30 seconds
- 40˚C for 30 seconds
- 72˚C for 2 minutes and 30 seconds
- Now we can add the (AT-BHO-F) primer to the reaction.
- 4˚C for 5 minutes
- 94˚C for 30 seconds
- 60˚C for 30 seconds
- 72˚C for 2 minutes and 30 seconds
- 72˚C for 10 minutes
- 4˚C to end
- The PCR products were run on a GelRed post-stained 2% agarose gel using a 1kb ladder for visualization
(This was repeated for another 35 cycles)
(This was repeated for another 4 cycles)
(This was repeated for another 31 cycles)
Experimental Design – Primer combinations and annealing temperatures:
Template | Primer pair | Annealing temp (degrees Celsius) | Number of cycles |
---|---|---|---|
(AT-FWD-RBS)-(AT-RVS-1)PCR product | (AT-BHO-F)-(AT-BHO-R) | 40, then 60 | 4, then 35 |
(AT-FWD-RBS)-(AT-AHO-R)PCR product | (AT-AHO-F)-(AT-AHO-R) | 60 | 35 |
(AT-FWD-RBS)-(AT-RVS-1)PCR product (1:10 dilution) | (AT-BHO-F)-(AT-BHO-R) | 40, then 60 | 4 then 35 |
(AT-FWD-RBS)-(AT-AHO-R)PCR product (1:10 dilution) | (AT-AHO-F)-(AT-AHO-R) | 60 | 35 |
Figure 5. PCR optimization (with ssPCR amplification for (AT-BHO-F)primer)
Discussion of gradient PCR:
The gradient PCR was used because the (AT-BHO-R) primer that was ordered was 12 base pairs shorter than what was supposed to be ordered. The (AT-BHO-R)primer was supposed to include the whole reverse primer sequence (18 base pairs) as well as an additional sequence for the HO site. This caused an issue with this primer annealing in previous PCR reactions. The gradient PCR will allow for this primer to anneal prior to any other primer annealing increasing the chance of annealing.
