We pick single column, and incubate in another tube.

We get “k89608” part and transform it.

Because transformation we did on 6/11 was fail, this week, we did transformation again.

In order to find the cause, we did two control group. One is J23102 the other is the kit provided. And we transform B0034 this time.

Material:

1. 70 % Ethanol
2. Isopropanol
3. 50 ml centrifuge tubes
4. Plasmid DNA Midi Kit
5. pSB1C3-BBa_B0030 in DH5α
6. pSB1C3-BBa_E1010 in DH5α
7. pSB1A2-BBa_E0040 in DH5α
8. pSB1A2-BBa_B0010 in DH5α

Notes:

1. Add RNase A to PL1 Buffer and store at 4℃
2. Warm PL2 Buffer in a 37℃ waterbath
3. Use 100~150 ml of bacterial culture for Midi Kit

Protocol:

1. Flick a PM Column 2~3 times, then place the PM Column on a conical flask.
2. Equilibrate the PM Column by applying 5 ml of PL4 Buffer by gravity flow
3. Harvest the bacterial culture 100 ml by centrifuge at 6000 x g for 10 mins
4. Add 5 ml of PL1 Buffer to resuspend the cell pellet by vortexing or pipetting
5. Add 5 ml of PL2 Buffer and mix gently by inverting the tube 10 times. DO NOT VORTEX!!!
6. Place for 10 mins at room temperature until lysate clears
7. Add 5 ml of PL3 Buffer and mix immediately by inverting the tube 10 times. DO NOT VORTEX!!!
8. Centrifuge at 15000g for 20 minutes or filtered with a filter paper
9. Apply the supernatant from step 8. to the equilibrated PM Column and allow it to flow by gravity flow.
10. Wash the PM Column by using PL5 Buffer 15 ml and allow the column empty by gravity flow.
11. Discard the filtrate.
12. Place PM Column in a clean centrifuge and apply 10 ml of PL6 Buffer to elute DNA by gravity flow
13. Using eluates from step 12. Add 7.5 ml of room temperature isopropanol. Vortex well and let the mixture sit for 2 minutes.
14. Centrifuge at 12500 x g for 30 minutes.
15. Remove the supernatant, then add 3 ml of 70% ethanol to wash.
16. Centrifuge at 12500 x g for 5 minutes, then dry ethanol at room temperature.
17. Apply 0.2 ml of TE Buffer to resuspend DNA.

We get “B0030, E0040, E1010”part,and transform them.

   We put all the result into fluorescent reader.

   

   This one is stand for Pb⁺.

   

   This one is stand for Cd²⁺.

We do the ligation, and then transform the plasmid into E.coli

Mixing with LB broth, we smear the solid on the plate.

This is our first time do the experience.

We are going to use the restriction enzyme to cut the sample part {E GFP} and add a part by ligation.

So first, we use enzyme to cut the plasmid, and use gel electrophoresis to cut our part.

Than we purify our gel.

7. LB plate(LB broth + 1% agar)
8. Antibiotics : Ampicillin & Chloramphenicol (100μg/mL for each)

Protocol:

1. Add 0.5μL of plasmid into 100μL of E.coli and mix by tapping the tube.(ps: the quantity of plasmid is dependent on bacterial competency)
2. Put the tube on the ice for 20~30mins.
3. Remove from the ice and put the tube to the 42℃ hot bath for 45 sec.
4. After heat shock, put the tube into the ice IMMEDIATELY for 2 mins.
5. Add 500 μL of LB broth into the tube and incubate for 30~60 mins at 37℃
6. Take out the tube and put into 6000 rpm centrifuge for 5 mins.
7. Remove supertant and remain about 100μL of LB to resuspend
8. Spread onto LB plate containing the appropriate antibiotic
9. Incubate overnight for 12~16 hrs at 37℃.

This week, we did transformation.

Preparing Samples

Homogenizing samples

• Determine your sample type, and perform homogenization at room temperature according to the table below. The sample volume should not exceed 10% of the volume of TRIzol Reagent used for homogenization. Be sure to use the indicated amount of TRIzol Reagent, because an insufficient volume can result in DNA contamination of isolated RNA.

RNA Isolation Procedurec

Always use the appropriate precautions to avoid RNase contamination when preparing and handling RNA.

RNA precipitation

1. (Optional) When precipitating RNA from small sample quantities (<10⁶ cells or < 10 mg tissue), add 5-10μg of RNase-free glycogen as a carrier to the aqueous phase.
   • Note: Glycogen is co-precipitated with the RNA,but does not inhibit first-strand synthesis at concentrations ≤4mg/mL,and does not inhibit PCR.
2. Add 0.5mL of 100% isopropanol to the aqueous phase, per 1mL of TRIzol Reagent used for homogenization.
3. Incubate at room temperature for 10 minutes.
4. Centrifuge at 12,000 × g for 10 minutes at 4℃.
   • Note: The RNA is often invisible prior to centrifugation, and forms a gel-like pellet on the side and bottom of the tube.
5. Proceed to RNA wash.

Proceed to RNA wash.

1. Remove the supernatant from the tube,leaving only the RNA pellet.
2. Wash the pellet,with 1mL of 75% ethanol per 1mL of TRIzol Reagent used in the initial homogenization.
   • Note: The RNA can be stored in 75% ethanol at least 1 year at-20℃, or at least 1 week at 4℃.
3. Vortex the sample briefly,then centrifuge the tube at 7500 × g for 5 minutes at 4℃.Discard the wash.
4. Vacuum or air dry the RNA pellet for 5-10 minutes. Do not dry the pellet by vacuum centrifuge.
   Note: Do not allow the RNA to dry completely,because the pellet can lose solubility.Partially dissolved RNA samples have an A_260/280 ratio<1.6.
5. Proceed to RNA resuspension.

RNA resuspension

1. Resuspend the RNA pellet in RNase-free water or 0.5% SDS solution(20-50㎕) by passing the solution up and down several times through a pipette tip.
   • Note: Do not dissolve the RNA in 0.5% SDS if it is to be used in subsequent enzymatic reactions.
2. Incubate in a water bath or heat block set at 55-60℃ for 10-15 minutes.
3. Proceed to downstream application, or store at -70℃.

Total:40ul

Plasmid DNA:500ng (77.7ng/ul, 500/77.7≒6.5ul)

1. Excise the DNA fragment from the agarose gel with a clean, sharp scalpel.
2. Weigh the gel slice in a colorless tube. Add 3 volumes Buffer QG to 1 volume gel (100 mg gel~100 μl).The maximum amount of gel per spin column is 400 mg.For>2% agarose gels,add 6 volumes Buffer QG.
3. Incubate at 50℃ for 10 min (or until the gel slice has completely dissolved). Vortex the tube every 2–3 min to help dissolve gel. After the gel slice has dissolved completely, check that the color of the mixture is yellow (similar to Buffer QG without dissolved agarose). If the color of the mixture is orange or violet, add 10μl 3 M sodium acetate, pH 5.0, and mix. The mixture turns yellow.
4. Add 1 gel volume isopropanol to the sample and mix.
5. Place a QIAquick spin column in a provided 2 ml collection tube or into a vacuum manifold. To bind DNA, apply the sample to the QIAquick column and centrifuge for 1 min or apply vacuum to the manifold until all the samples have passed through the column. Discard flow-through and place the QIAquick column back into the same tube. For sample volumes of&62;800μl, load and spin/apply vacuum again.
6. If DNA will subsequently be used for sequencing, in vitro transcription, or microinjection, add 500 μl Buffer QG to the QIAquick column and centrifuge for 1 min or apply vacuum. Discard flow-through and place the QIAquick column back into the same tube.
7. To wash, add 750μl Buffer PE to QIAquick column and centrifuge for 1 min or apply vacuum. Discard flow-through and place the QIAquick column back into the same tube. Note: If the DNA will be used for salt-sensitive applications (e.g., sequencing, bluntended ligation), let the column stand 2–5 min after addition of Buffer PE. Centrifuge the QIAquick column in the provided 2 ml collection tube for 1 min to remove residual wash buffer.
8. Place QIAquick column into a clean 1.5 ml microcentrifuge tube.
9. To elute DNA, add 50 μl Buffer EB (10 mM Tris·Cl, pH 8.5) or water to the center of the QIAquick membrane and centrifuge the column for 1 min. For increased DNA concentration, add 30 μl Buffer EB to the center of the QIAquick membrane, let the column stand for 1 min, and then centrifuge for 1 min. After the addition of Buffer EB to the QIAquick membrane, increasing the incubation time to up to 4 min can increase the yield of purified DNA.
10. If purified DNA is to be analyzed on a gel, add 1 volume of Loading Dye to 5 volumes of purified DNA. Mix the solution by pipetting up and down before loading the gel.
