Presentation Transcript

Procedure
Procedure

  • The Plasmid pBestluc

    and the CaCl must be kept on ice

    throughout the entire experiment.




6.Add 10ul (10 microliters) of the plasmid (pBestluc) using a yellow-tipped plunger micropopette, to your microcentrifuge tube.

  • Cap tube and gently tap with your finger to mix.

  • Incubate your tube on ice for 15 minutes.


9. While the tube is on ice, obtain your LB + ampicillin plate.

10. Using forceps or wearing gloves place a sheet of nitrocellulose paper on the surface of the agar.

11. Lift the lid only enough to place the Nitrocellulose paper on the agar and replace the lid ASAP


12. The bacterial cells must be HEAT SHOCKED in order to allow for plasmid transformation to occur.

13. After 15 min on ice, remove the tube and immediately place in a 42oC water bath for 75-90 seconds.


14. Remove tubes from bath and place on ice for 2 minutes allow for plasmid transformation to occur.

  • 15. Remove tubes from ice and add 0.25 (250 ul) of room temeprature Luria Broth using a sterile pipette.

  • 16. Finger-tap to mix.

  • 17. Tube may now be kept at room temp.


18. Using a clean pipette, add 20ml (200ul) of your plasmid/bacteria solution to the center of your Luria Agar plate covered with nitrocellulose paper. Cover the petri dish

** Repeat step 18 with your LB Agar Plate (w/o Ampicillin). DO NOT USE NITROCELLULOSE PAPER FOR THIS DISH)
