Shuffling Kit

How to use
What users should prepare
To use the kit, the protein sequence you chose must have specific prefix/suffix which contains a BsaI site and produce overhang. Therefore, users must design a primer to add it. To reduce time and trouble, we automated the design by creating program "Primer Designer for Maestro"!
Promoter Selector
What our kit contains
Our Promoter Selector consists of 5 different plasmids (table.1). Each has a promoter with a different strength. Downstream of the RBS there is a BsaI site to insert the protein sequence. There is a color expression construct downstream of protein insertion site (fig.1). Each color is paired with different strength promoter. The pairings are shown on the table below.
Part number | Promoter | Promoter strength | Paired protein | Protein color |
---|---|---|---|---|
BBa_K1084501 | BBa_K1084001 | Strongest | amilGFP | yellowish green |
BBa_K1084502 | BBa_K1084002 | Stronger | aeBlue | strong blue |
BBa_K1084503 | BBa_K1084005 | Medium | amilCP | Purple |
BBa_K1084504 | BBa_K1084009 | Weaker | mRFP | Pink |
BBa_K1084505 | BBa_K1084010 | Weakest | eforRED | red |

The color always expresses. LacZα reporter is placed between two BsaI sites (fig.2). The LacZα expressing construct will be replaced by chosen sequence using BsaI.

How it works
![](https://static.igem.org/mediawiki/2013/2/27/HokkaidoU2013_optimization_Fig7_ver2_400.png)
1. Have BsaI site and specific overhang added to your protein sequence (fig.3). PCR with primers designed with Primer Designer for Maestro should do the trick.
2. Digest and ligate your protein coding sequence and all our Promoter Selector together (fig.4). This is accomplished by "Golden Gate Assembly" reaction. The detailed recipe is shown in Engler (2009)[1]. All the protein coding sequence will be inserted in the plasmid.
![](https://static.igem.org/mediawiki/2013/a/ac/Fig4_131027_2_HokkaidoU_2013.png)
3. You should get the construct shown below after Golden Gate Assembly (fig.5).
![](https://static.igem.org/mediawiki/2013/a/a1/Fig5_131027_HokkaidoU_2013.png)
4. Transform the ligated DNA to E. coli, and spread it on plate. Then, you will get colonies with five colors easily because you can see 5 colors by naked eyes (fig.6). The colors are paired with the promoters, so you will know what promoter you are using without sequencing all the colonies. You can pick up colonies and have an assay.

RBS Selector
What our kit contains
Our kit contains tandem RBS (fig.7) and acceptor plasmid (fig.8).
![](https://static.igem.org/mediawiki/2013/2/22/RBS_strength_2_HokkaidoU_2013.png)
In this part, 4 strength levels of RBSs[BBa_K1084101, BBa_ K1084102, BBa_ K1084103, BBa_ K1084104] are connected in tandem. To optimize up to 3 coding sequence expressions in the operon this part has three sets of RBSs with different overhangs and they are connected together.
![](https://static.igem.org/mediawiki/2013/d/d5/HokkaidoU2013_optimization_Fig13_800.png)
How to use
1. Have BsaI site and specific overhang added to your protein sequence. Again, Primer Designer for Maestro should help your primers design (fig.9). Also when you want to apply more than one protein coding sites, add BsaI sites and overhang to them too. Be careful not to choose the same overhangs.
![](https://static.igem.org/mediawiki/2013/e/ef/HokkaidoU2013_optimization_Fig14_800.png)
2. Digest and ligate your protein coding sequences and all RBS Selector together. This reaction is also accomplished by Golden Gate Assembly. DNA fragments will be assembled in the desired order (fig.10).
![](https://static.igem.org/mediawiki/2013/7/7d/HokkaidoU2013_optimization_Fig15_ver.2_800.png)
3. Transform the ligated DNA to E. coli. If you are using three different proteins, you will get 64 different kinds of constructs.
We will submit these standard methods as RFC to BioBrick Foundation.
