Invitrogen™ T-REx™ Core Kit, with pcDNA™4/TO/myc-His© Vector 
Tetracycline-regulated expression system without viral transactivators
Supplier: Invitrogen™ K103002
Includes: 20μg of pcDNA4/TO or 20μg each of pcDNA4/TO/myc-His A, B, and C; a positive control vector, pcDNA6/TR, and forward and reverse sequencing primers. All vectors are supercoiled and provided lyophilized.
Description
- Uses complete CMV promoter and adds control elements from bacterial tetracycline resistance operon to effectively repress and derepress transcription from one of strongest mammalian promoter sequences known
- Specific Activation: uses repressor mechanism that blocks transcription from powerful CMV promoter in absence of tetracycline
- Because T-REx System elements do not use viral transactivators, can achieve high-level expression from complete CMV promoter without secondary, non-specific activation of host genes
- Two tetracycline operator sequences (TetO2) have been inserted between TATA box of CMV promoter and transcriptional start site
- TetO2 sequence itself has no effect on expression: When tetracycline repressor protein (TR) is present, it effectively binds TetO2 sites and blocks transcription initiation
- Tetracycline added to culture medium binds to, and changes conformation of, TR protein causing TR protein to release TetO2 sites and derepressing transcription from CMV promoter: The result is high-level expression of gene of interest
- Expression levels can be modulated based on tetracycline concentration and can be induced to levels that are achieved with constitutive CMV expression vectors
- Complete CMV enhancer-promoter sequence containing two copies of tetracycline operator TetO2 sequence for high-level regulated expression
- Zeocinor hygromycin resistance gene for effective selection of stable mammalian cell lines
- Large multiple cloning site to simplify cloning
- In addition, pcDNA™4/TO/myc-His offers a c-myc epitope for rapid detection of recombinant protein with Anti-myc Antibody and polyhistidine (6xHis) sequence for simple purification of recombinant protein with nickel-chelating resin and detection with Anti- His(C-term) Antibody
- Regulatory vector, pcDNA™6/TR, is provided for high-level expression of tetracycline repressor (TR) protein
- Vector expresses Blasticidin resistance gene for rapid selection of mammalian cell lines that stably express TR protein
