Contruction of pET3a Derivatives Containing bchD and bchI

1. Amplify Rhodobacter's gene and introduce restriction sites by PCR (Using Phusion Polymerase), which allow cloning PCR fragments into pET3a

bchD bchI
length of gene fragment 1695 b.p. 1005 b.p.
Restriction sites introduced when amplified by PCR NdeI, BamHI NdeI, BglI


2. Do DNA Gel Electrophoresis to confirm that the length of the PCR fragments are the same as the corresponding target gene fragments.

3. Remove any leftover PCR enzyme in the samples by PCR Clean Up/Purification.

4. Digestion for PCR Products using specific restriction enzymes

bchD NdeI, BamHI
bchI NdeI, BglI

4. Digested bchD and bchI are subjected to Gel Extraction to ensure that only pure, digested DNA is obtained before doing ligation.

5. Ligate digested and purified PCR fragments with digested pET3aLigation yielding plasmids of pETBCHD and pETBCHI.

6. Use small portion of the plasmids to do Analytic Digestion

7. Do KCM Competent Cell Transformation to subclone plasmids into DH10B competent cells, which have been done by KCM Competent Cell Production.
