Recombinant DNA Bacterial TransformationTeacher Preparation Sterile Materials
Recombinant Transformations • Sterilized Materials List • (per group of students) • 1 pack of 8-10 toothpicks wrapped in aluminum foil • 1 pack of 4 large paper clips bent at 90o wrapped in aluminum foil • 50 ml Sterile Calcium Chloride solution • 50 ml Sterile Water
Recombinant TransformationSterile Materials(per group of students) • 1 aluminum foil packet containing 8-10 toothpicks
Recombinant TransformationSterile Materials(per group of students) • 1 aluminum foil packet containing 4 large, smooth paper clips. The clips should be opened into a 90° angle and the small ends bent up.
Recombinant TransformationSterile Materials • Heat the foil packages containing paper clips and toothpicks at 350oF for at least 30 minutes to sterilize.
Recombinant TransformationCaCl2 Solution • Dissolve 0.75 g of CaCl2 into 50 ml of distilled water in a labeled 100-ml glass bottle with a cap.
Recombinant TransformationCaCl2 Solution • Cap the bottle and place it in boiling water for 30 minutes. Cap should be "snugged" down on the bottle. • Refrigerate to prevent contamination.
Recombinant Transformation Sterile Distilled Water • In a bottle with a cap, add 50 ml of distilled water. • Cap the bottle and place it in boiling water for 30 minutes. Cap should be "snugged" down on the bottle. • Refrigerate to prevent contamination.
