| |
| - | In the first round of PCR, we amplified fragments required for the assembly of GA1, GA2, GA3 and GA4 constructs.
| |
| - | *We performed PCR using [[Team:Cambridge/Protocols/PCR#Reagents_used_in_PCR_reaction | Phusion Hot Start DNA Polymerase]] in 20 μl reaction volume.
| |
| - | *The time profile used in the PCR machine was the following:

| - | We decided to use the 55°C annealing temperaure, although the predicted temperature for most primers is 5-10°C higher, because of a low annealing temperature of the VF2 primer.
| |
| - | *Primers and template DNA provided by our supervisor Paul served as a positive control, but eventually we did not detect any products on the gels.

| - | The pictures below present result of gel electrophoresis of PCR products.
| |
| - | *In most cases position of a band matches the expected length of DNA fragment. The only exception are GA1-2 and GA3-2 products. According to the position on the gel the length of these DNA fragments is 4-5kb, whereas the predicted length is 3.5kb. Our hypothesis is that we were provided [http://partsregistry.org/Part:pSB1AK3 pSB1AK3] backbone instead of [http://partsregistry.org/Part:pSB1A3 pSB1A3]backbone.
| |
| - | *For GA1-1, GA2-1, GA3-1 and GA4-1 we obtained two bands -
| |
| - | *The molecular weight marker that we used in all gels is HyperLadder I, which produces regularly spaced bands ranging from 200 to 10,000bp.
