March 11, 2007: Motility Assay Experiment Aims

Test motility on a variety of surface hardnesses in order to determine optimal level to use for assays.

Procedure

Eiken Agar Plates were made using a modified version of general procedure 1. Increased agar concentrations were made to increase hardness of gel and reduce the speed of motility.

.20% Eiken Agar Plates: .30% Eiken Agar Plates: .40% Eiken Agar Plates:
 * .25g Bactotryptone
 * .20g NaCl
 * .15g sodium citrate
 * .05g Eiken Agar (for 20EikenAgar)
 * .25g Bactotryptone
 * .20g NaCl
 * .15g sodium citrate
 * .075g Eiken Agar (for 30EikenAgar)
 * .25g Bactotryptone
 * .20g NaCl
 * .15g sodium citrate
 * .10g Eiken Agar (for 40EikenAgar


 * 1) Constructs were transformed into RP3087
 * 2) *YFP Sender Cells-Sender (LVA+)-RP3087 w/ [I14032+B0030+C0161 A3]+E0430
 * 3) *Sender Cells-Sender-RP3087 w/ I14032+B0030+C0161 (B2)
 * 4) *Receiver-RFP+Receiver-RP3087 w/ I13321+[J09855+B0033+J09274]
 * 5) Grown overnight at 37 degrees C on 50 micromolar Kan LB plates
 * 6) 3mL cultures inoculated off of the plate and grown at 30 degrees C until OD590~.45
 * 7) 3uL placed of receiver cells placed in various distances from 3uL inoculated sender colony.

Results:

Observations:

.20% agar plate difficult to handle as agar was extremely fragile. Results were diminished by heavy diffusion. .30% agar results in fair motility and is much easier to handle .40% agar results in no motility

Conclusions:

Future Experiments:

Retry .20% Agar experiments with set distances away from sender Experiment with temperature changes

May 15, 2007: General Procedures These are all the general cloning kinds of things that will be used to build our constructs. We will probably get into getting parts sequenced if things do not seem to be working, but that gets expensive and takes a couple of days, so my thoughts are we should save that until it looks like we are getting into trouble. Labeling is key.

Labeling
 * 1) First note this is the most important thing for how easy it is. In the past we have had a lot of problems however so I have come up with a system.  Remember everyone is going to need to be able to read this, so use a fine tipped sharpie always.  Also EtOH is an organic solvent and will remove your title.  Be careful with this especially during minipreps.  Write on the outside of the tube, Thats really obvious it would seem, but just a warning.

Microcentrifuge tubes On Cap: On Side: you may want to duplicate all the information especiall if it is very messy or you needed more room.

EX-on Cap: On Side:

Innoculation from plate
 * 1) flame loop
 * 2) cool loop on plate
 * 3) pick up individual colony
 * 4) place in culture and shake loop
 * 5) flame loop

Culture Dilutions EX 1-1:100 Dilution
 * 1) Add 3mL fresh LB to a new culture tube
 * 2) Add 3uL of appropriate (1:1000)antibiotic solution
 * 3) Take 30uL from starter culture and place in fresh media.
 * 4) *Becareful to not touch the sides of the tube with the pipetmen.

'''Checking cell OD. Using Spectrophotometer''' note: wavelength for DNA = 260nm, wavelength for protein=280nm, to find purity take ratio between peaks.
 * 1) Turn on spectrophotometer (switch on the back to the right)
 * 2) Allow the startup to run, and then turn off deuterium Light (needed at hv <300nm)
 * 3) Turn wavelength to 590nm
 * 4) Zero with 1mL LB in Cuvette
 * 5) Do an appropriate dilution (suggested 1:5, 1:10) of culture with fresh LB into a fresh Cuvette
 * 6) *note 1: if you are trying to find out how long it will be until cells are at OD .6 (mid log) you can take the OD at two seperate times and use http://molbiol.edu.ru/eng/scripts/01_02.html.
 * 7) *note 2: diluting a culture down to OD .6 will not put it in mid log phase; dilute down to .15 and allow it to grow back up to .6 if your culture has grown too long.

Miniprep
 * 1) Spin down 3mL of saturated cell culture, remove supernatant
 * 2) Resuspend pelleted bacteria in 250uL Buffer P1 and transfer to a 1.5mL micro centrifuge tube.
 * 3) Add 250uL Buffer P2 and invert the tube gently 4-6 times to mix.
 * 4) Add 350uL Buffer N3 and invert the tube immediately but gently 4-6 times.
 * 5) *the solution should be come cloudy
 * 6) Centrifuge for 10 minutes at 13,000 rpm in a table-top microcentrifuge
 * 7) *allign tubes such that the cap clip is facing outward
 * 8) decant supernatant into spin column
 * 9) Centrifuge for 60s. Discard flow-through.
 * 10) Add .75mL Buffer PE and centifuge for 60s.
 * 11) Discard flowthrough and centrifuge for 60s
 * 12) Place the spin column into a new 1.5mL microcentrifuge tube.
 * 13) Add 30-50uL of water (8.5>pH>7) to the center of each spin column.
 * 14) Let tubes stand vertically for 1min, then centrifuge for 1min.

Digest
 * 1) Add components generally by largest volume to smallest. I tend to add water first just so I do not waste pipettips if I am using different vectors, but cetainly do not start with .5 or 1 uL components.
 * 2) Choosing your Enzymes: The biobricks are built with the restriction sites as following: -EcoR1-Xba1-Part-Spe1-Pst1- it is important to remember that your plasmid may have some of these restriction sites too, so if too many bands are appearing on the gel becareful of this. Keep these enzymes on ice when they are out of the feezer, and put them back immediately after you use them.  If enzymes happen to be left out please let me know and we will decide what to do with them.  Do not put enzymes that have been left out back in the freezer, or future restrictions will not work.
 * 3) Choosing your buffer: Check the compatibility with each enzyme and the buffer. There should be a list for double digestions.
 * 4) Forgetting to add BSA will make the whole thing not work.

EX1-10uL Digest
 * Examples demonstrate the two main digets that will be used in this lab.
 * 1) 3.0uL H2O
 * 2) 4.0uL Vector
 * 3) 1.0uL Buffer X
 * 4) 1.0uL BSA
 * 5) 0.5uL Enzyme 1
 * 6) 0.5uL Enzyme 2

EX2-20uL Digest
 * 1) 4.0uL H2O
 * 2) 11.uL Vector
 * 3) 2.0uL Buffer X
 * 4) 2.0uL BSA
 * 5) 0.5uL Enzyme 1
 * 6) 0.5uL Enzyme 2

Running a Gel TAE Buffer-if you are extracting from your gel TBE Buffer-for better imaging Do not load DNA in high concentrations. It may be tempting to put in as much concentrated DNA as you can, but this is not a good thing.

May 22, 2007: Growing Parts From Registry Plates Registry plates are kept in the -4 degree freezer in a box labeled registry plates.
 * 1) Take a 10uL pipetment and pipet 10uL of dd-water up and down inside target well on the registry plate
 * 2) Once the water appears red place that in a labeled microcentrifuge tube (Initials Date, Part name well #, and ID number).
 * 3) *Now the registry part is ready to be transformed. Proceed with regular transformation.

Motility Information

July 6, 2007: Motility Assay Experiment Aims

Test motility at a variety of different temperatures.

Procedure

Eiken Agar Plates were made using a modified version of general procedure 1. An ncreased agar concentration was made to increase durability of plate and reduce the motility.

.28% Eiken Agar Plates:
 * .25g Bactotryptone
 * .20g NaCl
 * .15g sodium citrate
 * .07g Eiken Agar (for 20EikenAgar)


 * 1) Receiver cells grown at 37 degrees to OD500 ~1.2
 * 2) *Rediluted to OD500 ~ .2 and grown for 1.5 hours at 30 degrees
 * 3) .3uL plated of receiver cells with 1uL of sender cells (.3uL used with wildtype RP4037)
 * 4) grown at temperatures 21, 26, 30, and 37C

Controls
 * Motile Strain RP4037
 * +HSL Plate
 * -Sender Cell Plate

Results:

Observations:

21 degree plates have no exhibited swarming as of ~14 hours. 26 degree plates seemed quite successful with controls, however room temperature may have dropped from 26 to 22 overnight 30 degree plates wild type cells swarmed very quickly when compared to controls 37 degree plates exhibited leaky expression in negative control

Conclusions:

Future Experiments:

Try a variety of agar concentrations at the 26 degree temperature

July 10, 2007: Changing the sender to a high copy plasmid Part BBa_F1610 was grown up off registry plate and transformed into DH5a. Motility assay will be retried Wednesday.

Digested P1010 PSB1A2 Gel extracted Ligated with Extracted products 7/10 in LW-1 Transformed

July 16, 2007: Testing what we have and preparing for sequencing Grew up 6-7 colonies per plate of ligations. (large numbers on negative plates, thus a quck miniprep, and subsequent digestion should reveal if the constructs were made.

Also, a gigantic gel was made to test the dna concentration of everything we have. The full list can be found in Noah's lab notebook.

July 23, 2007: Motility Assay Protocol Motility Protocol: note: <.25% plates are difficult to deal with as they break very easily (Weiss motility assay 3/11/07) .26%-.32% is what I tend to use. Cells did not swarmed at .40% agar concentration (Weiss motility assay 3/11/07) -LWeiss
 * 1) For each plate to be made, add the following to a 125mL flask:
 * 0.25g Bacto tryptone
 * 0.20g NaCl
 * 0.15g sodium citrate
 * 0.075g Eiken agar (for a 0.30% agar swarm plate)
 * 1) Add 25mL purified water to the flask and swirl to dissolve
 * 2) Autoclave 25 minutes with slow exhaust
 * 3) Upon cooling, add appropriate antibiotics and inducers
 * Kan 50µg/mL
 * Amp 100µg/mL
 * HSL between 10-4 - 10-8
 * IPTG 1mM
 * 1) Allow plates to solidify for ~3 hours before use
 * Plates can be prepared the previous day before inoculated, but tend to try out if prepared too far in advance-LW

Day 1: Inoculate O'N Culture
 * 1) Inoculate 3mL overnight cultures of all samples to be tested
 * 2) Shake at 200 RPM in 30°C incubator
 * I have done this at 37°C and it seems to be ok, I would recommend shaking at whatever temperature the motility assay will be run at-LW

Day 2: Assay
 * 1) Dilute overnight culture 1:100 in LB (30uL of culture in 3mL LB)
 * 2) Grow in a 30°C incubator at 200 RPM to an A590nm O.D. between 0.3-0.4
 * 3) Add about .5µL-3µL of each culture to plates
 * 4) Grow in a 26-30°C incubator 8 hours
 * At 37°C our constructs tend to swarm regardless of HSL’s presence-LW (motility assay 7/8/2007)
 * 1) Take picture of plate with digital camera
 * I prefer to monitor the cells over a 20 hour period.-LW
