description
Transcript of Overexpression of Orf2 in Mycobacterium sp. strain JC1
Overexpression of Orf2 in Mycobacterium sp. strain JC1
Order the primer to clone orf2 (pProEX™HTa vector 고려 )
Perform PCR with produced primer using Mycobacterium sp. strain JC1 chromosomal DNA
Elution PCR product and ligation with pGEM-T easy vector
Transformation into E.coli DH5α
Sequencing the cloned pGEM-T easy vector containing PCR product
Ligate with pProEX™HTa for overexpression
Transformation into E.coli DH5α
Plasmid prep & Transformation into E.coli BL21
A preliminary Experiment Induction by IPTG (25℃ & 37℃)
Confirm expression patterns using SDS-PAGE
Induce at 37℃ for 5hr & Harvest -20℃ 보관
