| |
| - | We chose to concentrate on four polar tags found in Caulobacter Crescentus. Previous research indicated that DivJ and StpX genes were responsible for polar
| |
| - | localization to the stalk side of the cell. Conversely PflI and TipF were chosen as candidates for polar localization to the non-stalk side or flagella
| |
| - | side of the cell. These tags were chosen because they appear to be present in the cell during the stalked cell part of the life cycle in Caulobacter
| |
| - | Crescentus. The stalked cells with holdfast like stalk structures are ideal for creating biofilms.
| |
| - | </p>
| |
| - | <p dir="ltr">
| |
| - | Attempts to isolate the polar tag genes from Caulobacter Crescentus involved designing PCR primers which flanked the gene of interest. Restriction sites
| |
| - | were also added to the primers to allow for generation of fusion proteins. Generally we used Touchdown PCR cycles to attempt to amplify the polar tags out
| |
| - | of the genome. Next the polar tags were ligated into expression vectors which contained either YFP or CFP on the C-terminal side of the multiple cloning
| |
| - | sites. These recombinant plasmids were then transformed into competent e.coli cells for plasmid amplification. The amplified plasmids were isolated and
| |
| - | sequenced before being transformed back into into Caulobacter.
| |
| - | </p>
| |
| - | <p>
| |
| - | We also identified a possible minimal (DivJM) polar tag consisting of only 235bp. This minimal DivJ was assembled using overlapping 60 mers synthesized and
| |
| - | amplified in a PCR reaction.

| |
| - | the agarose solution in the microwave. Let the agarose solution cool and pour it into the casting tray and let the agar solidify. Remove comb from the
| |
| - | agar. Remove the casting tray from the gel box. Place the gel tray with the gel back into the gel box such that the ends of the gel are pointed into the
| |
| - | buffer reservoirs on either end and the end of the gel with wells is pointed towards the negative electrode. Add TBE buffer to the gel box until both
| |
| - | reservoirs are full and a 1-2 mm layer of TBE buffer covers the top (flat side facing up) side of the gel. Load samples and DNA ladder on the gel. Slide
| |
| - | the lid and connect the electrodes to the power supply. Run the gel for 1 hour at 120 V. After gel run, take a photograph using the gel documentation
| |
| - | apparatus.

| |
| - | The primary goal of the Biofilm Membrane team was to produce a high-density monolayer biofilm. A monolayer biofilm structure is critical to the function of
| |
| - | the biomachine as the overall goal of the project is to move salt across a membrane, producing potable water. Caulobacter Crescentus (C. crescentus), is a
| |
| - | polar body bacteria that forms high density monolayer biofilms and has been well characterized to support its use in biotechnological applications. The
| |
| - | biofilm forming capabilities of a strain of C. crescentus (CB15) have been well characerized by a group at Stanford University whose work we have cited.
| |
| - | CB15 was obtained from the Standford lab for the purpose of this project.

| |
| - | <u>Procedure:</u>
| |
| - | </p>
| |
| - | <p>
| |
| - | 1. Make 4% PFA, 1X PBS, 0.1% Triton-X-100, and DAPI stock conc. 1ug/ml (prepare these by looking at protocols). Do all work w/ PFA in fume hood.
| |
| - | </p>
| |
| - | <p>
| |
| - | 2. Using a new 12 well culture plate, fill a well up w/ 4ml of DH20.
| |
| - | </p>
| |
| - | <p>
| |
| - | 3. Take a coverslip to be analyze, wash slip by transferring it to the well w/ 4ml of dH2O for 2mins w/ gentle shaking (in order to get rid of swarmer and
| |
| - | unattached cells.)
| |
| - | </p>
| |
| - | <p>
| |
| - | 4. Do this next step in fume hood, since we are going to work w/ PFA. Aspirate dH2O and replace medium w/ 4ml of 4% PFA. Leave coverslip in solution for 8
| |
| - | minutes and place plate on a nutator. Do not leave it in there for more than 10mins.
| |
| - | </p>
| |
| - | <p>
| |
| - | 5. Aspirate 4% PFA medium. PFA is volatile so dumped liquid waste onto paper towels that should be wrapped in aluminum foil before disposal.
| |
| - | </p>
| |
| - | <p>
| |
| - | 6. Wash cells by inoculating 4ml of 1x PBS into well for 5mins. Place plate on a nutator. Repeat this process 2 more times (wash cells w/ 1x PBS for a
| |
| - | total of 3 times.)
| |
| - | </p>
| |
| - | <p>
| |
| - | 7. Remove 1X PBS and add 4ml of 0.1% Triton-X-100 (to permeabilize cells). Leave coverslip in there for 10mins. Also place plate on a nutator.
| |
| - | </p>
| |
| - | <p>
| |
| - | 8. After 10mins, repeat step 6. Wash cells 3 times w/ 1X PBS (5mins/wash.)
| |
| - | </p>
| |
| - | <p>
| |
| - | 9. Stain cells by inoculating well w/ 4ml of DAPI for 5mins. Place plate on a nutator.

| |
| - | <strong>Protocol</strong>
| |
| - | :
| |
| - | </p>
| |
| - | <p>
| |
| - | 1) Confirm if supply of pre-culture is available.
| |
| - | </p>
| |
| - | <p>
| |
| - | Preparing a pre culture: Using a pipette tip pick a colony from CB15 plate (from Stanford) dip it in 5ml PYE+amp. Incubate this at 200rpm and 33degrees C
| |
| - | overnight.
| |
| - | </p>
| |
| - | <p>
| |
| - | 2) Prepare glass cover slips by cleaning with w/ ethanol. There’s 10% ethanol in lab if not we can make 10% ethanol by adding 100ml of ethanol to 900ml
| |
| - | dH20. Squirt some ethanol on coverslips and wipe them away with KimWipes.
| |
| - | </p>
| |
| - | <p>
| |
| - | 3) Next sterilize glass pieces, PYE, dH2O, and forceps by autoclave at 120°C for 40 mins on fluid cycle
| |
| - | </p>
| |
| - | <p>
| |
| - | 4) Sterilize plastic pieces by using ethanol and rinsing off w/ sterile dH20

| |
| - | </p>
| |
| - | <p>
| |
| - | 5) Place a cover slip in each well of tissue culture plate. We will have a total of 10 culture plates testing 3 different parameters (temps, days, and
| |
| - | replacement of nutrients) See figure for experiment layout.

| |
| - | <p>
| |
| - | 6) Add 2mL of PYE to each well.
| |
| - | </p>
| |
| - | <p>
| |
| - | 7) Identify negative control wells.
| |
| - | </p>
| |
| - | <p>
| |
| - | 8) Before inoculating check OD600 of preculture.
| |
| - | </p>
| |
| - | <p>
| |
| - | Procedure for spectrometer: Turn on the spectrometer, there’s a switch on the back of the machine. Hit option 4 Cell Count. Zero the machine out w/ a blank
| |
| - | (do this by filling a cuvette w/ PYE, place it in the machine, and hit auto zero.) There should be an arrow on the cuvette, turn the arrow until it faces
| |
| - | left and place it in the spectrometer. Read numbers off the top right. It should say 600nm and 0.00. Next pipette out 200ul of culture into another
| |
| - | cuvette, place it in the machine, and read off the top right corner or press start and it’ll pop out a number (this is the OD at 600nm).
| |
| - | </p>
| |
| - | <p>
| |
| - | 9) Inoculate each well that is to receive culture with 10uL of pre culture (CB15)
| |
| - | </p>
| |
| - | <p>
| |
| - | 10) Incubate at 33°C at 300rpm in incubator
| |
| - | </p>
| |
| - | <p>
| |
| - | <strong>To take a data point</strong>
| |
| - | </p>
| |
| - | <p>
| |
| - | 11 to take a data point at the 24hr interval, remove the coverslip to be analyzed. Use sterile forcep to handle coverslip. Wash coverslip to remove swarmer
| |
| - | and unattached stalked cells by preparing a petri dish filled w/ 15ml PBS (can also use a well and fill it w/ 2ml dh20). Place coverslip in PBS water for 2
| |
| - | min with gentle shaking.
| |
| - | </p>
| |
| - | <p>
| |
| - | (Rough graph for planning. Data points will include pictures of different staining methods. Look at different a protocol for staining)

| |
| - | <u>Procedure:</u>
| |
| - | </p>
| |
| - | <p>
| |
| - | 1. Make 4% PFA, 1X PBS, 0.1% Triton-X-100, and DAPI stock conc. 1ug/ml (prepare these by looking at protocols). Do all work w/ PFA in fume hood.
| |
| - | </p>
| |
| - | <p>
| |
| - | 2. Using a new 12 well culture plate, fill a well up w/ 4ml of DH20.
| |
| - | </p>
| |
| - | <p>
| |
| - | 3. Take a coverslip to be analyze, wash slip by transferring it to the well w/ 4ml of dH2O for 2mins w/ gentle shaking (in order to get rid of swarmer and
| |
| - | unattached cells.)
| |
| - | </p>
| |
| - | <p>
| |
| - | 4. Do this next step in fume hood, since we are going to work w/ PFA. Aspirate dH2O and replace medium w/ 4ml of 4% PFA. Leave coverslip in solution for 8
| |
| - | minutes and place plate on a nutator. Do not leave it in there for more than 10mins.
| |
| - | </p>
| |
| - | <p>
| |
| - | 5. Aspirate 4% PFA medium. PFA is volatile so dumped liquid waste onto paper towels that should be wrapped in aluminum foil before disposal.
| |
| - | </p>
| |
| - | <p>
| |
| - | 6. Wash cells by inoculating 4ml of 1x PBS into well for 5mins. Place plate on a nutator. Repeat this process 2 more times (wash cells w/ 1x PBS for a
| |
| - | total of 3 times.)
| |
| - | </p>
| |
| - | <p>
| |
| - | 7. Remove 1X PBS and add 4ml of 0.1% Triton-X-100 (to permeabilize cells). Leave coverslip in there for 10mins. Also place plate on a nutator.
| |
| - | </p>
| |
| - | <p>
| |
| - | 8. After 10mins, repeat step 6. Wash cells 3 times w/ 1X PBS (5mins/wash.)
| |
| - | </p>
| |
| - | <p>
| |
| - | 9. Stain cells by inoculating well w/ 4ml of DAPI for 5mins. Place plate on a nutator.
| |
| - | </p>
| |
| - | <p>
| |
| - | 10. Wash cells w/ 1X PBS for 5 mins.
| |
| - | </p>
| |
| - | <p>
| |
| - | 11. Coverslip is now ready to be analyzed
| |
| - | </p>
| |
| - | <p>
| |
| - | 12. See microscopy protocol.

| |
| - | <p>
| |
| - | 12 Well Tissue Culture Plate x 10
| |
| - | </p>
| |
| - | <p>
| |
| - | 40 Glass coverslips 15mm
| |
| - | </p>
| |
| - | <p>
| |
| - | 40 Filter Paper 0.22 micron
| |

| |
| - | <strong>Protocol</strong>
| |
| - | :
| |
| - | </p>
| |
| - | <p>
| |
| - | 1) Confirm if supply of pre-culture is available.
| |
| - | </p>
| |
| - | <p>
| |
| - | Preparing a pre culture: Using a pipette tip pick a colony from CB15 plate (from Stanford) dip it in 5ml PYE+amp. Incubate this at 200rpm and 33degrees C
| |
| - | overnight.
| |
| - | </p>
| |
| - | <p>
| |
| - | 2) Prepare glass cover slips by cleaning with w/ ethanol. There’s 10% ethanol in lab if not we can make 10% ethanol by adding 100ml of ethanol to 900ml
| |
| - | dH20. Squirt some ethanol on coverslips and wipe them away with KimWipes.
| |
| - | </p>
| |
| - | <p>
| |
| - | 3) Next sterilize glass pieces, PYE, dH2O, and forceps by autoclave at 120°C for 40 mins on fluid cycle
| |
| - | </p>
| |
| - | <p>
| |
| - | 4) Sterilize plastic pieces by using ethanol and rinsing off w/ sterile dH20
| |
| - | </p>
| |
| - | <p>
| |
| - | <strong>See figure for layout (these steps done for each different surface type)</strong>
| |
| - | </p>
| |
| - | <p>
| |
| - | 5) Place a cover slip in each well of tissue culture plate. We will have a total of 10 culture plates testing 3 different parameters (temps, days, and
| |
| - | replacement of nutrients) See figure for experiment layout.

| |
| - | </p>
| |
| - | <p>
| |
| - | 6) Add 2mL of PYE to each well.
| |
| - | </p>
| |
| - | <p>
| |
| - | 7) Identify negative control wells.
| |
| - | </p>
| |
| - | <p>
| |
| - | 8) Before inoculating check OD600 of preculture.
| |
| - | </p>
| |
| - | <p>
| |
| - | Procedure for spectrometer: Turn on the spectrometer, there’s a switch on the back of the machine. Hit option 4 Cell Count. Zero the machine out w/ a blank
| |
| - | (do this by filling a cuvette w/ PYE, place it in the machine, and hit auto zero.) There should be an arrow on the cuvette, turn the arrow until it faces
| |
| - | left and place it in the spectrometer. Read numbers off the top right. It should say 600nm and 0.00. Next pipette out 200ul of culture into another
| |
| - | cuvette, place it in the machine, and read off the top right corner or press start and it’ll pop out a number (this is the OD at 600nm).
| |
| - | </p>
| |
| - | <p>
| |
| - | 9) Inoculate each well that is to receive culture with 10uL of pre culture (CB15)
| |
| - | </p>
| |
| - | <p>
| |
| - | 10) Incubate at 33°C at 300rpm in incubator
| |
| - | </p>
| |
| - | <p>
| |
| - | <strong>To take a data point</strong>
| |
| - | </p>
| |
| - | <p>
| |
| - | 11 to take a data point at the 24hr interval, remove the coverslip to be analyzed. Use sterile forcep to handle coverslip. Wash coverslip to remove swarmer
| |
| - | and unattached stalked cells by preparing a petri dish filled w/ 15ml PBS (can also use a well and fill it w/ 2ml dh20). Place coverslip in PBS water for 2
| |
| - | min with gentle shaking.
| |
| - | </p>
| |
| - | <p>
| |
| - | (Rough graph for planning. Data points will include pictures of different staining methods. Look at different a protocol for staining)
