AAV with ALB(1.7) promoter driven iCre
Cat. No: VB1603
Availability:
2-3 weeks
Name:
AAV-ALB(1.7)-iCre
This AAV expresses iCre driven by a liver ALB(1.7) promoter.
The ALB(1.7) is a shorter version of the ALB(1.9) promoter with a total length of 1.7 Kb. In mouse liver cells, the transgene expression from this ALB(1.7) synthetic promoter is about 3-5 times lower than that of the ALB(1.9) promoter but 20-200 fold greater than that of the CMV promoter 10-20 weeks after plasmid injection into mouse liver.
Cre is a recombinase from the P1 bacteriophage. This enzyme carries out site-specific recombination between two DNA recognition sites (LoxP sites) through a topoisomerase I-like mechanism. The Cre recombinase here has been codon-optimized leading to a higher level of Cre protein expression (iCre). The 34base pair (bp) loxP recognition site, ATAACTTCGTATA ATGTATGC TATACGAAGTTAT, consists of two 13 bp palindromic sequence which flank an 8 bp spacer region. The products of Cre-mediated recombination at loxP sites are dependent upon the location and relative orientation of the loxP sites. For example, two separate DNA species both containing loxP sites can undergo fusion as the result of Cre-mediated recombination. DNA sequences found between two loxP sites on the same DNA molecule are said to be floxed. In this case, the products of Cre-mediated recombination depend upon the orientation of the loxP sites: DNA found between two loxP sites oriented in the same direction will be excised as a circular loop of DNA, whereas DNA between two loxP sites that are oriented oppositely will be inverted. Besides LoxP sites, other Lox sites have been designed and tested, such as Lox272 and LoxN etc. These Lox elements have been widely used for genetic studies
