Objective: Transfer aminoacyl RNA synthetases from thermophile genomic dna into non-thermophillic plasmids, and transform into DH10B cells

1. Isolate aminoacyl tRNA synthetases from thermophillic genomic DNA via PCR with designed oligos.
2. Digest target vector (pBad-myc/hisA) and tRNA synthetase pcr products.
3. Ligate each pcr product into vector
4. Transform each ligation reaction
5. Pick colonies, grow cultures, and miniprep DNA for sequencing

Thermophile: thermatoga maritma
tRNA synthetases: Ala, Asp, Cys, Lys, Leu, Ile, Glu, Phe, His, Gly
Vector: pBad-myc/hisA

march 4: Make 13 pcr products of tRNA-synthetases using expand buffer

24 ul ddH2O
3.3 ul 10x Expand Buffer "2"
3.3 ul dNTPs (2mM in each)
1 ul Oligo 1, 10 uM
1 ul Oligo 2, 10uM
0.5 ul, Expand polymerase "1"
0.5 ul Template ENA

march 6: Run gel on pcr products that require soeing (leucine and alanaine)

1. run gel on leu1, leu2, ala1, ala2.
2. make second gel, run remaining 9 samples for diagnostics.
3. gel purify leucine and alanine, zymoclean other pcr products
4. run two pcrs for soeing

Last couple of days:

Completed soeing pcrs successfully

Digest of all pcr products (did not digest enough vector)
run gel of digested product, melt in ADB

Cheryl He 13:20, 20 March 2014 (EDT)

Run gel to double clarify contents of two tubes (vector or asp) Zymocleanup of vector
