Using DNA distribution kit plates: Rehydration of registry DNA from kit plate

Wells in the DNA distribution kit plates contain 2-3 ng of dry DNA. This should be enough DNA for a few transformation, but insufficient for immediate restriction and ligation.

Materials

• DNA distribution kit plates
• Sterile distilled water
• Micropipette
• Sterile micropipette tip

Protocol

1. Locate the well with the DNA part you need
2. Using a micro pipette, draw 10 μL sterile distilled water into a sterile pipette tip
3. Use the pipette tip to puncture a hole through the cover foil and into the well containing DNA you need.
4. Release the water into the well and pipette up and down a few times to rehydrate the DNA you need
5. Store the re-hydrated DNA in the -20C freezer. You can either leave it in the original plate, or transfer it into a separate tube (make sure to label the tube!).
6. The rehydrated DNA can be used immediately to transform competent cells. As little as 1 μL should be enough for one transformation.

Restriction Digest

This protocol is for cutting approximately 500ng of plasmid with two different restriction enzymes. This should provide enough cut DNA for both ligation and agarose gel electrophoresis.

Materials

• Plasmid DNA
• 10x Restriction buffet
• Sterile distilled water
• Restriction Enzymes(EcoR1, Spe1, Xba1, and Pst1)
• Thermocycler
• (0.6 mL) Microcentrufuge tube
• Microcentrifuge
• Ice
• Micropipettes and Sterile pipette tips
• Water bath and 37C

Protocol

1. Thaw all solutions and buffers needed. Homogenize the contents by gently flicking the tube. If possible, collect all liquid at bottom of tube by spinning briefly in the microcentrifuge at maximum speed. Place tubes on ice.
2. Label a sterile 0.6 mL microcentrifuge tube with an identifying label for the particular restriction digestion you’re doing. Make sure that you use a permanent marker and the tube fits inside the heating block of your thermocycler.
3. Pipette the following into the tube in the order listed. It adds up to a total volume of 20 μL
4. Mix gently by pipetting up and down a few times. You can bring all the liquid to the bottom of the tube by spinning it briefly in the microcentrifuge at maximum speed.
5. Incubate at 37 °C in water bath or thermocycler for 30 minutes to 1 hour.
6. Incubate at 80 °C for 20 minutes. This will denature the restriction enzymes, which otherwise may interfere with subsequent steps.
7. Store the restriction digests in - 20 °C freezer, or proceed immediately with ligation and/or agarose gel electrophoresis.
