| - | '''Procedures'''
| |
| - | # Start thawing the competent cells on crushed ice.
| |
| - | # Add 50 µL of thawed competent cells and then 1 - 2 µL of the resuspended DNA to the labelled tubes. Make sure to keep the competent cells on ice.
| |
| - | # Incubate the cells on ice for 30 minutes.
| |
| - | # Heat shock the cells by immersion in a pre-heated water bath at 42ºC for 60 seconds. A water bath improves heat transfer to the cells.
| |
| - | # Incubate the cells on ice for 5 minutes.
| |
| - | # Add 200 μl of SOC broth (make sure that the broth does not contain antibiotics and is not contaminated)
| |
| - | # Incubate the cells at 37ºC for 2 hours while the tubes are rotating or shaking. Important: 2 hour recovery time helps in transformation efficiency, especially for plasmids with antibiotic resistance other than ampicillin.
| |
| - | # Label two petri dishes with LB agar and the appropriate antibiotic(s) with the part number, plasmid, and antibiotic resistance. Plate 20 µl and 200 µl of the transformation onto the dishes, and spread. This helps ensure that you will be able to pick out a single colony.
| |
| - | # Incubate the plate at 37ºC for 12-14 hours, making sure the agar side of the plate is up. If incubated for too long the antibiotics start to break down and un-transformed cells will begin to grow. This is especially true for ampicillin because the resistance enzyme is excreted by the bacteria, and inactivate the antibiotic outside of the bacteria.

| - | # Begin BioBrick Assembly with three separate plasmids, an upstream part, a down stream part, and a destination plasmid. It is important that the destination plasmid contain the toxic gene ccdB in the BioBrick cloning site and a different antibiotic resistance to the upstream and downstream parts. | + | |
| - | # Digest each part with the proper restriction enzymes to isolate the upstream and downstream parts, and to remove the BioBrick from the destination plasmid.
| + | |
| - | # Ligate the products. The result will be the upstream part connected to the downstream part in the destination plasmid. This new composite part can then be used to transform competent cells.

| |
| - | # Begin by thawing the upstream, downstream, and destination plasmid parts along with the NEBuffer 2 and BSA.
| |
| - | # In three separate PCR microcentrifuge tubes labeled upstream, downstream, and destination, add 500ng of the respective dried DNA and dilute with dH20 to 42.5 uL.
| |
| - | # Add 5 uL of NEBuffer 2 and 0.5 uL of BSA to each tube.
| |
| - | # Add 1 uL of the first appropriate enzyme to each tube. Then add 1 uL of the second appropriate enzyme.
| |
| - | # Flick each tube to mix reagents and incubate at 37C for 15 minutes.
| |
| - | # Transfer the tubes to an incubator set at 80C for another 20 minutes. This step will deactivate the restriction enzymes.
| |
| - | # Digestion is now finished and products should be stored at -20C.
