- Genome extraction

- Gene isolate using PCR
- Normal primer design and gradient PCR to amplify the gene.
- Normal primer design and gradient PCR to amplify the gene.
- Site mutation
- Using the primer design by us, follow these tips:
1,Full length not less than 28bp; 2, 3'end to mutation site not less than 18bp; 3, Mutation site to 5' end not less than 10bp.
- Gene purification ,Enzyme digest, ligation and transformation
In our experiment, we found the vector (we used) is hard to digest by two enzyme in the same time, it cost us a long time on the identification the correct plamid, unfortunately, it was frustrating. at last, we follow the advice from the teacher, degest one by one, and have an self-ligation test in order to have the correct digested vector.
- In-fusion cloning and tranformation
we use this method for the ligation of 6 genes, but follow the instrction of the Clontech company, we may waste a lot of money on it, so we search methods from the paper, first, we test four-way ligation, however, it turn out to be no colony. so we test three-ligation. it was useful.
Methods are as follows:
Vector: more than 50ng;
Gne inserts: more than 5:1 molar ratio to vector
In-fusion enzyme: 2ul every 10ul reaction system
ddH2O: Add water to 10ul
- Sequensing
Done by company
- Colony PCR Plasmid extraction
Colony PCR sometimes was not as convenient as we thougt. Sometimes plasmid extraction is better!
- Double Digestion for chek
- Temperament chromatography
for the function test of the degradation of the two enzyme gene.
