| - | ===July 1st, Sunday===
| |

| |
| - | Because we learned that our SYBR Green was causing ladder to run strangely, Dylan decided to redo a [[Vent PCR]] to amplify the salicylate reporter region out of p21.
| |
| - | <br>
| |
| - | Liquid culture of JG700.
| |
| - | <br>
| |
| - | Replated p21, p22, JG700, JG1220, JG1537, JG1219

| |
| - | Today, Dylan and Caleb ran a [[Team:Cornell/DNA Gel Electrophoresis|gel]] of a [[Team:Cornell/Vent PCR|Vent PCR]] of p21 (the PCR product being the salicylate reporter) at 55 V. Additionally, Caleb decided to run a control gel at 100 V to determine whether higher voltage was a factor in our previous ladder problems (in addition to the SYBR Green stock). While we determined that the higher voltage did not cause our ladder issues, we did not see any bands from the p21 PCR.

| |
| - | Dylan prepared electrocompetent cells using the Myers and Myers protocol. Modified protocol using 2 5mL cultures @ 4000g for 10 min. Washed with 2 mL sorbitol, resuspended in 100 uL sorbitol. First electroporation ts = 2.32 ms, seconf ts = 2.02 ms. Added 1 uL of plasmid (575.5 ng) to each cuvette. First used .60 V, then 0.55 V, both with R = 400 ohms.

| - | Mark and Danielle started liquid cultures of S1, S9, S10, S11, S15, S16, S18, S27 (See: [[Team:Cornell/Vent PCR|Strain list]])

| - | ===July 3rd, Tuesday===
| |
| - | Caleb [[Team:Cornell/Miniprep|miniprepped]] S16 (p15), S22 (p21), S9 (p8), S10 (p9), S11 (p10), S18 (p17), and S15 (p14). Instead of a single EB elution, Caleb did two elutions, 30 ul each. The double 30 ul elution turned out to be effective at recovering a usable amount of DNA in the second elution, so we're including it on our miniprep protocol.

| |
| - | The rerun of our Gibson sequencing failed again, so wetried a more roundabout method of determining whether our 3 Gibson transformants are complete Nah operons or not. We digested them each with BamHI, expecting specific fragment lengths on a gel electrophoresis.
