Purpose : After being subjected to restriction digestion using di ff erent enzymes (Uncut, EcoR1, BamHI, and E+B), the resulting fragments of E.coli JM101 were separated using gel electrophoresis. 1. Work in partners .As a pair you will complete the following reactions 2. Get four 1.5 mL microcentrifuge tubes and label them “Uncut”, “EcoR1 ”, “BamHI”, “and “E +B” and your initials 3. Look at the four tables below and add the appropriate components to each tube: Component: Uncut Volume Autoclaved dH 2 O 6 μ L Loading Dye 2 μ L 250 ng Plasmid DNA. 2 μ L TOTAL 10 μ L A B 1 2 3 4 5 6 THURSDAY, 2023-11-30 Table1 Explore the Notebook

Gently mix the tube by pipetting up and down. If there is liquid on the sides of the tube give it a quick spin in the centrifuge. 2. Place the digest tubes (EcoRI, BamHI, E + B) in 37 C water bath for 15 min . Do NOT put the uncut plasmid tube in the water bath. It just stays on your bench. Loading Gel: 1. 0.75% agarose gels containing 1X Red Safe (FroggaBio) will be already prepared and in TBE running bu ff er. 2. Your TA will load a 1Kb plus ladder (FroggaBio) in the fi rst lane of the gel. 3. You will load 8 μ L of each of your restriction digests. 4. Once all samples are loaded the gel will be run at 120V for approximately 45 min. 5. The gel picture will be posted to OWL. Table4
