Golden Gate iGEM Parts

Send iGEM-Parts easyer and faster to the iGEM-Registry.

Because we worked during our work only with Golden Gate Systems, we had the problem how to send these parts to the iGEM - Registry. But we had an idea. What is if we combine Golden Gate Standard with the FC10 iGEM Standard?

The PCRs

First of all, each Part and also the Vector pSB1C3 has to tranform into GoldenGate Standards with BbsI cut sites.

As you can see in the picture 1 we designed the primer, for each parts in this way that these have the cutsites for the igemregistry and also for BbsI.

The Vector pSB1C3 got also the Cutsite for BbsI in this way, that the BbsI recognition site was removed at the assembly.

And also for each part the primer was designed in this way, that they contain the cutsites for BbsI, EcoRI, NotI, XbaI, SpeI and PstI.

PCR Method

The Method for each PCR was a standard method for Q5 (from NEB)

Name	Volume
Q5 High-Fidelity 2X Master Mix	25 µL
10 µM Forward Primer	2.5 µL
10 µM Reverse Primer	2.5 µL
Template DNA	2 µL
Nuclease free water	18 µL

Cleanup Protocol for PCR Product

For the cleaning of the PCR products we use a standard PCR/Gel Extraction kit. The Product was eluted in 50 µL Elution Buffer or Tris-HCl pH 8.

Golden Gate Cloning Protocol

For the Golden Gate Cloning we use a concentration of 40 nM for the vector and 80 - 120 nM for the inserts. (Ratio 1:2 vector:insert or Ratio 1:3 vector:insert) The calculation was as following:

Plasmid-Name	Nanodrop [µg/µL]	Final Conc. [nM]	Factor 1ng/ul -> 1nM	Conc Stock [nM]	Dilution	DNA [µL]	Tris-HCl [µL]
pSB1C3	150	40	0.78374	39.187	2.9	68	132
GFP	150	100	0.78374	39.187	2.5	80	120

We used a standard assay for the assembly. From each diluted part we used 1 µL and mixed it with a Golden Gate MasterMix consists of BsaI or BbsI, T4 Ligase, CutSmart-Buffer, ATP and water.

After Golden Gate Assembly, the whole volume (20 uL) was transformed into competent E. coli cells.
