           2. 98°C        8s
           3. 61°C        30s
           4. 72°C        1:10m
           5. Go to 2 for additional 29 cycles
           6. 72°C        10m
           7. 4°C         ---


Amplification introduces sites SpeI-rbs and NotI-BglII into the gene.

2. Amplification is followed by DNA Gel Electrophoresis is used to confirm that the length of the PCR fragment is the same as the corresponding gene (~2kb).

3. PCR Clean Up/Purification

4. Restriction Digestion of gene S-chlD with SpeI and NotI using the following conditions:

Schl-D Sequential Restriction Digestion: 

           Digestion #1
           43 ul Schl-D
           5 ul NEB 2 (10x)
