Construction of pET3A-(S)-chlH:
1. Amplify Synechocystis-Cyanobacteria gene S-chlH by PCR (Using Phusion Polymerase) using the following conditions:
PCR: 1 ul Synechosystis (10ng/ul) 10 ul HF Buffer 5x 1 ul dNTP 5 ul primer mix 0.5 ul Phusion 32.5 ul H2O -------------- 50 ul total
Conditions: 1. 98°C 30s 2. 98°C 8s 3. 56°C 30s 4. 72°C 2:10m 5. Go to 2 for additional 29 cycles 6. 72°C 10m 7. 4°C ---
Amplification introduces sites NdeI and KpnI-BamHI 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 (~4kb).
4. Restriction Digestion of gene S-chlH with NdeI and BamHI using the following conditions:
Schl-H 41 ul S-chlH fragment 5 ul NEB 3 (10x) 0.5 ul BSA (100x) 1.8 ul NdeI 1.2 ul BamHI ------------------ 50 ul total
Digest in 37°C for 2 hours.
Add 0.5 ul NdeI and 0.5 ul BamHI.
Digest in 37°C for additional 30 minutes.
5. DNA Gel Electrophoresis is used to confirm the correct band of ~4kb.
6. Gel Extraction is performed to isolate the correct band(~4kb).
7. pET3A:
Innoculate pET3A single colony from plate into 250 mL flask containing 50 mL LB + 50 ul Carb. Allow to grow in 30°C shaker overnight.
Miniprep cultures.
Restriction Digestion of plasmid pET3A with enzymes NdeI and BamHI using the following conditions:
42.1 ul pET3A plasmid 5 ul NEB 4 (10x) 0.5 ul BSA (100x) 1.2 ul NdeI 1.2 ul BamHI --------------------- 50 ul total
Gel Extraction is performed to isolate the correct band(~5kb).
8. Ligate S-chlH to plasmid pET3A", yielding plasmid "pET3A-(S)-chlH"
4.5 ul pET3A 12.5 ul S-chlH 2 ul Ligase Buffer 1 ul Ligase Enzyme ------------------- 20 ul total
9. Transformation into Novablue cells using KCM Competent Cell Transformation using the following conditions:
7 ul pET3A-(S)-H ligation 73 ul H2O 20 ul KCM solution 100 ul Chemical Competent Novablue/DH10B cells ----------------------------------------- 200 ul total
Plate onto LB Agar + Carb plate
10. Innoculate single colonies into separate 4mL LB + 4mL Carb culture tubes and let grow overnight in 30°C.
11. Miniprep cultures
12. Analytic Digestion using the following conditions:
20 ul DNA 3 ul NEB 4 (10x) 1 ul NdeI 1 ul SpeI 3 ul BSA (10x) 2.0 ul H2O ------------- 30 ul total
Run gel – look for ~4kb and ~5kb band
Save glycerol stocks
13. Transformation into BL21 cells via KCM Competent Cell Transformation:
2 ul pET3A-(S)-H-Novablue 100 ul BL21 cells 20 ul KCM (5x) 78 ul H2O ---------------------------- 200 ul total
15. Protein Analysis using SDS-PAGE
