| Biosafety Level： | 1 |
| Vector Information： | Size (kb): 5.5999999046325680 Vector: pTEX (plasmid) Promoters: Promoter T3 Construction: T. cruzi gGAPDH, pMC1neo, pBluescript KS Marker(s):G418R,ampR,neoR Construct size (kb): 5.599999904632568 Features: marker(s): ampR, neoR, G418R promoter: gGAPDH I, T3, T7 replicon: pMB1 terminator: gGAPDH II |
| Applications： | expression vector shuttle vector vector permitting RNA synthesis in vitro |
| Comments： | Restriction digests of the clone give the following sizes (kb): PstI--4.8, 0.65, 0.2; BamHI--5.6; EcoRI--5.6; KpnI--5.6. The neoR gene can be used as a selectable marker in Trypanosoma cruzi and Leishmania. Increasing the concentration of G418 in the media increases copy number and expression. Shuttle expression vector for Trypanosoma cruzi and Leishmania. Transfected DNA is maintained in transformed parasites extrachromosomally as circular head-to-tail tandem repeats. DNA can be rescued from transformed parasites and propagated in E. coli after linearizing and religation to produce single circular copies. The order of the major features in this plasmid is: SacI - SacII - 5 flanking region of gGAPDH I - SpeI/MCS/XhoI - PstI - gGAPDH I/gGAPDH II intergenic region - neoR - gGAPDH II 3 flanking region - KpnI - ampR - pBluescript KS. |
