Gel Electrophoresis
- The double digest (pSB1C3) from yesterday was run on a 1% gel.
- This was done in order to confirm that the digest worked and also to purify the pSB1C3 vector.
- Sample 1.1 - track 2
- Sample 1.2 - track 3
- Sample 2.1 - track 4
- Sample 2.2 - track 5
- The 2 Kb bands are the pSB1C3 backbone
- The 1 Kb bands are the RFP biobrick
The two higher bands in tracks 2 and 3 are plasmids that were not digested.
Gel purification of the pSB1C3 backbone and RFP biobrick
- The Zymoclean Gel DNA recovery Kit was used to perform the purification and its protocol was followed.
- However the elution step was changed to 12ul of elution buffer, and this step was repeated.

Double digest of TOD genes PCR products
Samples A (TodX), C (TodF) and E (ToBG) were digested with the enzymes XbaI and SpeI.

- The samples were incubated at 37C for 90 minutes
- Heat kill the enzymes by incubating the samples at 80C for 20 minutes
