Objective
To determine whether or not the synthesis of mutated GFP DNA was successful through gel electrophoresis.
Description
- Add 0.25 g of 0.01 g/mL agarose to 25 mL of 1x tris base, acetic acid, and ethylenediaminetetraacetic acid (TAE) buffer. Heat the solution in a microwave for 40 seconds. The result is a 1% agarose gel used in electrophoresis. Pour the solution into the gel container with the appropriate dams. Allow the gel to cool for approximately 20 minutes.
- Mix 1 μL of 6x gel loading dye with 5 μL of the mutated DNA sample.
- Load the samples with dye mixture and a ladder containing DNA, glycerol, and gel loading dye into the wells of the gel. The ladder used was as follows: 500 bp, 1000 bp, 2000 bp, 3000 bp, 4000 bp, 5000 bp, 6000 bp, 7000 bp, 8000 bp, 9000 bp, 10000 bp.
- Run the gel electrophoresis at 80 V for 40 min.
- Remove gel and place in TAE and ethidium bromide (EtBr) solution, mix for 15 min.
- Rinse gel with TAE for 5 min.
Data
All groups were successful in the synthesis of the mutated DNA. The desired product was 3600 bp. Using a UV light, we were able to see the DNA of all groups located between the 3000 bp and 4000 bp ladder spots, indicating a successful synthesis.
