AAV with ALB(1.4) promoter driven TdTomato

This AAV expresses TdTomato driven by a liver ALB(1.4) promoter.

The ALB(1.4) is a shorter version of the ALB(1.7) promoter with a total length of 1.4 Kb. In mouse liver cells, the transgene expression from this ALB(1.4) synthetic promoter is about 3 times lower than that of ALB(1.7) promoter but 10-100 fold greater than that of the CMV promoter 10-20 weeks after plasmid injection into mouse liver.

dTomato belongs to a family of fluorescent proteins called mFruit. Two dTomato units were joined head-to-tail through a linker, yielding a tandem dimer fluorescent protein, tdTomato. The tdTomato derivative is the brightest fluorescent protein yet reported, featuring an orange-red emission maximum at 581nm and is one of the most photo-stable fluorescent proteins. Other fluorescent proteins with similar emission spectra include DsRed, DsRed2, TurboRFP, TagRFP, and TagRFP-T.
