Ligation: samples digested on the 13th of September
Ligation pairs: plasmid / insert :
BBa_B0014 / BBa_C0012
First report:
Plasmid = 2µL
Insert = 5µL
Second report:
Plasmid = 1,5µL
Insert = 5µL
Third report:
Plasmide = 1µL
Insert = 7µL
NEB Enzymes
For each samples add sterilized water to obtain a maximum volume equals to 8µL.
Ligation mix (NEB):
1,5µL T4 ligase + 1,5µL T4 ligase buffer.
Add 2µL / tube.
Incubation 1h at RT.
= TAKARA DNA ligation kit
First report:
Solution A (Buffer) = 28µL
Solution B (Enzyme) = 7µL
Incubation 1h at 16°C.
Electroporation
Electroporation cuvettes = 2mm ; inoculums of electrocompetent E.coli DH5alpha= 40µL; pulse = 2,5KVolt ; 1h of incubation.
Spread 1mL of inoculums into a petri dish with LB + ampicillin (50mg/mL) (20/0,02mL).
PCR
D protein
Primers:
Forward : Préfixe ATG BBa
Reverse : Prt D_Rv_Bal1
ADN :
1. Lambda bacteriophage;
2. Purified and amplified D protein.
Cycles:
94°C 2minutes;
(94°C 1 minute;
46°C 1 minutes;
72°C 1 minute(s)) X 35;
72°C 4 minutes;
Penton base from the adenovirus 5
Primers:
Forward : ADV5Fw_Bal1
Reverse : ADV5Rv_Bal1
ADN :
Purified and amplified penton base from plasmid coding for adenovirus 5.
Cycles:
94°C 2minutes;
(94°C 1 minute;
57,3°C 1 minutes;
72°C 2 minute(s)) X 35;
72°C 5 minutes;
DNA electrophoresis
85 Volt, 15 minutes.
105 Volt, 40 minutes.
Ladder fermentas 1 Kb.
Samples: Adenovirus penton base, D protein
Interpretation:
We obtain a small amplification for D protein on the sample 4. But other samples have bad results, we obtain to much DNA for samples 1 and 2 PCR, we also amplified the wrong DNA, maybe we use a bad temperature for primers annealing, finally sample 3 is negative.
