| MscL and MscS are mechanosensitive ion channels, respectively triggered due to large or small distending of their bacterial cell's lipid bilayers. They are in effect a 'last ditch response' to physical stress which might result in fatal osmolarity changes. MscL is a five subunit protein, each subunit being comprised of two transmembrane helices. MscS is a

| <b>Goal:</b> Digest and extract out the E0-gfp and ligate after the R0-promoter, into that pre-cut plasmid.

|
| |
| 1. Miniprepped the 3 BioBricks Plasmids (according to [http://openwetware.org/wiki/Miniprep/Qiagen_kit standard protocol])
| |
| *Made glycerol stocks of 1mL of the cultures from each transformant:
| |
| 666.6uL of 50% glycerol (to give 20% glycerol total)
| |
| 1mL of transformant culture
| |
|
| |
| 2. Double digested the 2 R0 (lac promoter) and 2 E0 (gfp) samples
| |
| *NB: Due to the NanoSpec reading out negative DNA concentrations, we proceeded with an arbitrary amount of transformed DNA for the digests.
| |
| *Digested with SpeI and PstI (NEBuffer 2) for R0, XbaI and PstI (NEBuffer 3) for E0, with the following protocol:
| |
|
| |
| ====Digest Protocol====
| |
|
| |
| DIGEST PROTOCOL
| |
| ----------------
| |
| 8uL miniprepped DNA
| |
| 2.5uL 10x NEBuffer
| |
| 2.5uL 10x (diluted 1:10 from the 100x stock) BSA
| |
| 1uL enzyme 1 (diluted 1:2 on Parafilm from the stock, of which we would have needed 0.5uL)
| |
| 1uL enzyme2 (1:2)
| |
| 10uL dH2O
| |
| ----------------
| |
| For a TOTAL VOLUME of 25 uL
| |
| Incubated 1 hr @ 37%degC
| |
|
| |
| *Deactivated the enzymes by placing on 80%deg heat block for 15 min.
| |
|
| |
| 3. Dephosphorylated 2 R0 samples to prevent self-ligation
| |
| *Added 1 unit (1uL of 1:10 dilution from the 10,000U/mL stock, of which we would have needed 0.1uL) of CIP (Calf Intestine Phosphatase) to the 2 R0 reactions.
| |
| *Incubated at 37%deg for 1hr.
| |
|
| |
| 4. Ran R0 and E0 samples on gel to separate out the gfp from the E0-plasmid
| |
| * Ran at 130V for ~45 min.
| |
|
| |
| 5. Gel extracted R0 plasmid (~2.1 kb, linearized by digestion) and E0 gfp fragment (~0.9kb)
| |
| *Cut out the 1 bright E0 0.9kb band and the 2 bright R0 2.2kb bands
| |
| *Extracted using the standard Qiagen protocol.
| |
|
| |
| *Froze overnight at -20%deg.
| |
|
| |
| ===Tu 6.13.06===
| |
| 1. Picked Colonies of Existing BioBrick Transformants
| |
| *Picked and numbered:
| |
| 3 colonies of E7,
| |
| 2 colonies of E0,
| |
| 2 colonies of R0.
| |
| *Grew each colony in 5mL LB + 5uL of 50mg/mL Amp (1:100 dilution).
| |
|
| |
| 2. Ran Gel of DNA Nanostructures
| |
| *Ran 2% agarose gel of the nanostructure reaction and the 2 controls for ~40 min at 130V. (NB: Only left four lanes are ours.)

| 1. Folded DNA Nanostructures Using Shawn's Pre-designed Oligo Staples and Scaffold ssDNA
| |
| *Three reactions below were mixed according to [http://openwetware.org/wiki/Folding_DNA_nanostructures given protocol].

| 2. Transformed Bacteria with Existing BioBrick Plasmids
| |
| *Transformed each BioBrick plasmid below into OneShot Top10 competent cells (Invitrogen) according to the following protocol.
| |
| R0010 (lac operon promoter),
| |
| E7104 (T4 promoter + gfp),
| |
| and E0241 (gfp).
| |
|
| |
| ====Top10 Transformation====
| |
| Thaw cells; aliquot out ~30uL per transformation.
| |
| Add desired amount of plasmid DNA (1 uL in this case?) to cells and leave on ice for 30 min.
| |
| Heat shock at 37°C for 30 sec in a heating block.
| |
| Ice for 2 min.
| |
| Shake in 37%deg incubator for 1 hr.
| |
| Pour onto plates with the required antibiotic (carbinomycin in this case); spread with beads or plate spreader.
| |
| Incubate plates in 37%deg incubator overnight.
