6/14-18/10 (Boot Camp)
DNA extracted from kit
Part: [http://partsregistry.org/partsdb/get_part.cgi?part=BBa_I746200]
6/22/10
We poured our Kan, Amp, Tet, Kan+Amp, Kan+Tet, Amp+Tet antibiotic agar plates.
Antibiotic Concentrations
- Amp: 50mg/500ml
- Kan: 31.97mg/500ml
- Tet: 6mg/500ml
6/23/10
Resuspended 12O and 6G DNA from the iGEM Kit and transformed them into our competent cells.
6G = r0010(inducible promoter) 12O = e0840(rbs30-gfp-2xterm)
6/24/10
Ran a gel of our PCR product to make sure that our taq polymerase master mix was working.
Selected single 12O and 6G colonies and transferred them to LB and incubated for 18 hours.
Let 1 12O and 1 6G plate incubate at RT. Let 1 12O and 1 6G plate incubate at 37°C. Intended to observe lawn growth.
6/25/10
Low DNA yield; Plan to redo DNA extraction from Kit
Found red/pink colonies in 12O plates. Thought to be contaminations. Plates were thrown out.
6/28/10
Kit to Stock
- 1-12O (e0840: rbs30-gfp-2xterm)
- 1-6G (r0010: inducible promoter)
- 3-20M (K124017: Bacteriophage Lysis Cassette S105, R, and Rz)
Plates were incubated at 37°C overnight (starting at 2:30 pm).
6/29/10
Selected single 1-12O, 1-6G, 3-20M colonies and grew them in Amp-LB broth for 18 hours (starting at 4:15 pm).
6/30/10
Poured 2 Sleeves of Kan and Amp plates respectively
Met with Dr. Russin (BIF)
Sent emails regarding biofilm and biofilm imaging: Aaron Packman, Wei Zhang, Kimberly Grey
Most likely going to use water immersion Leica (Confocal Microscope) + low MP agar (enrobing technique)
Red colonies reappeared on 1-12O plates; Fluorescent Microscopy revealed negligible activity; still unsure why colonies are red.
Miniprepped 1-12O, 3-20M, 1-6G: nanodrop -> mostly below 20ng, 1 above 100ng; stored in -20°C
Re-miniprepped after growing in liquid LB for 3 hours; nanodrop -> around 50ng/μL, 2 around 100ng/μL; stored in -20°C
Transferred overnight cultures into new 5ml LB broths. Incubated overnight in an angled shaker (starting from 4:20pm)
Plated 10μl, 25μl, 100μl, and 200μl (added LB up to 200μL) of the KR 1-12O overnight culture. Intend to measure the thickness of E.Coli lawn.
7/1/10
First weekly meeting with Professor Jewett, Leonard, and Mordacq.
Removed overnight cultures from incubator at 10:00am. Miniprep (let the elution buffer sit for 10 minutes with the DNA before centrifuging) --> 1 around 30ng/μL, mostly around 75ng/μL.
Started PCR of the chitin synthase gene using yeast genome.
Kit to Stock
- 1-12O (e0840: rbs30-gfp-2xterm)
- 1-12M (e0240: rbs32-gfp-2xterm)
- 1-6G (r0010: inducible promoter)
Plates were incubated at 37°C overnight.
