Day 6: DNA verification and DNA manipulation

Assignments Due

Overview of Experiment

In today's lab, you analyze the PCR reactions for the whole plasmid PCR on an agarose gel. You also perform a restriction digest on the whole plasmid PCR of BBa_I13522: pTetR-GFP to destroy the vector template before performing transformation.

Agarose gel analysis of PCR products

  1. Prepare a mini 1% agarose gel with one 8-well comb (use ~40 ml molten agarose) as on Day 2 [3 teams will share one gel]
  2. Preparation of PCR samples:
    a. Spot 1 µl 6X loading buffer (LB) on a piece of parafilm (one spot for each PCR sample)
    b. Remove 5 µl from the 1st PCR tube, mix it with one spot of 6X LB by pipetting up and down, and load the sample into a well
    c. Repeat procedure for each PCR reaction
  3. Load 10 µl 1 kb DNA ladder
  4. Run the gel at 130 V for ~20 min
  5. Photograph the gel and compare the observed bands to the standards

DpnI digestion of PCR products

  1. Divide the remaining PCR sample for the mutated RBS in half
  2. Add 1 µl DpnI (NEB Catalog #R0176S) to one of the PCR samples
  3. Incubate both PCR samples at 37°C for 1 hour
  4. Inactivate at 80°C for 20 min.
  5. Store samples at -20°C
