AAV with SST promoter driven TdTomato

This AAV expresses TdTomato driven by an islet SST promoter.

The rat SST gene (also known as SS-14, SS-28, or Smst) is synthesized in the pancreatic islets, gastrointestinal tract, nervous system, and thyroid gland. The promoter (SSTp) is a 0.9Kb regulatory fragment from the rat SST gene.

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.
