Enzyme Digest Protocol 1

Step 1 - Thawing cells: Thaw all materials on ice

Step 2 - Adding Ingredient: Add the following ingredients to autoclaved/sterile eppendorf tubes

Component Amount (ul) (one enzyme used) Amount (ul) (two enzymes used)
dH20 2.5 1.5
Buffer 1x 1 1
DNA template 5 5
BSA 0.5 0.5
Enzyme 1 1 2
Enzyme 2 N/A 1


Step 3 - Addition of BioBrick: Flick contents gently and centrifuge.

Step 4 - Centrifuge:

RPM: 14000

Time: 1 minute

Temperature: 18oC

Step 5 - Digest Program: Place the samples on a thermocycler under the following conditions:

RPM: 550

Time: 2.5 hours

Temperature: 37oC

Step 6 - Denaturing Enzymes: If you are not running the samples on a gel immediately, denature the restriction enzymes by running the samples on a thermocycler under the following conditions:

RPM: 550

Time: 25 minutes

Temperature: 65oC
