CRE recombinase

About CRE Recombinase:

CRE Recombinase  (click to see its codon sequence), from bacteriophage P1, catalyzes recombination between two LoxP sites (5′- GAAGTTCCTATTCTGTATTTATACGAAGTTAT -3′). Purified CRE enzyme can join individual plasmids containing lox sites.

CRE Expression Lentivirus:

GenTarget provides premade CRE expression lentivirus that can catalyze the joining of lox sites  in vivo. with following features.

  1. Those lentivirus contain the nuclear localization signal (NLS), PKKKRKV from the SV40 Large T-antigen at its N-terminus, allowing penetration of the nuclear membrane and thereby increasing the number of in vivo recombination events.
  2. CRE is expressed under an optional inducible CMV promoter (TetCMV), or an enhanced EF1a promoter, or a CAG promoter to best fit different cell type.
  3. The CRE Expression Lentivirus also a fluorescent or antibiotic selection, or fluorescent-antibiotic fusion dual selection. 
  4. Gentarget also provides CRE, luciferase, and fluorescent marker (GFP/RFP) triple-labeled lentivirus.

See the  lentivector structure diagrams below:

CRE expression lentivector schemes

CRE-lentivirus-map-scheme

Lentivirus are provided as  in two formats:

  1. Crude Lentivirus: 200ul /vial in DMEM containing 10 x Polybrene;
  2. Concentrated lentivirus: 200ul PBS solution which is better for hard-to-transduced cell types or for serum-free culture.

Note: Ultra-concentrated virus (>= 109 IFU/ml) is available upon special requests.

Please see each Product Manual below for details.
