Introduction
The 3A Assembly Kit and protocol will take you through the process of 3A Assembly, and by the end you will have assembled your own composite part in the lab. The kit includes two parts: Part A (BBa_J04500) and Part B (BBa_J04650), which when assembled together will form a RFP (red fluorescent protein) generator. Your cells will turn red!
The protocol will take you through the following steps:
1. Growing
 |
Grow up the E. coli that contains your parts! Your kit includes agar stabs for Part A (BBa_J04500) and Part B (BBa_J04650). The agar stabs contain live bacteria (E. coli) that house your parts. The parts themselves belong to a plasmid which replicates within the E. coli cell. So before working with your parts, you'll need to make sure you have enough copies of them. You can do this by growing up your E. coli from the stabs. More E.coli means more plasmids which means more copies of a part. Use these agar stabs to streak out your bacteria onto an agar plates. Then from the agar plate you can pick a single colony to grow up a cell culture. |
2. Miniprepping
 |
Miniprepping cell cultures to extract the DNA for your parts. You now have cell cultures of E. coli containing lots of copies of Part A (BBa_J04500) and Part B (BBa_J04650). In order to access the part DNA that you want, you'll need to lyse the cells (make them burst open), separate the DNA from the cellular material, and purify the sample to make sure you only have the plasmid DNA and not the E. coli's own genomic DNA. |
3. Restriction Digest
 |
Cutting the DNA for your parts and the pSB1C3 linearized plasmid backbone in a restriction digest Now that you have Part A and Part B, you'll want to cut them out from their pSB1AK3 plasmid backbones. You'll use restriction enzymes (provided by NEB) to cut the parts out. This will leave small overhangs at the end of each part which will eventually act like connectors to assembled them together. |
4. Ligation
| Ligating your two parts together into the pSB1C3 linearized backbone After your restriction digest you'll have Part A, Part B, and the pSB1C3 linearized plasmid backbone cut. Now you'll need to assemble all of these components together (Part A + Part B, into pSB1C3). You'll do this through the use of the overhangs (connectors) you've created by cutting the DNA with restriction enzymes and ligase, which will keep everything glued together. |
5. Transformation
| Transforming the ligation to get your newly assembled composite part. At the end you should see red colonies! You now have an assembled product through ligation (Part A + Part B, in pSB1C3). To get this new part into E. coli cells, you'll need to use a process called transformation. You'll need to make the provided NEB 10-beta strain competent, so it can uptake you ligated product (the plasmid containing your new part). Once the cells have taken in your plasmid, you'll grow them on a chloramphenicol plate (only cells containing the pSB1C3 plasmid backbone will live), and from those cells that live, there will be red colonies that have the correct new part. |
6. Post your results!
Note: The 3A Assembly Kit also includes prepared plasmid DNA for your Parts A and B, so you can skip directly to step 3 if you'd like.
