AAV with mIP2 promoter driven TdTomato

This AAV expresses TdTomato driven by an islet mIP2 promoter.

This promoter is based on the 1.1 Kb regulatory region of mouse pre-proinsulin II gene, also known as ins2, ins-2, ins-II, insulin-II, or Mody4. It is commonly used for beta cell-specific gene expression in the pancreatic islet. (m)INS2 promoter is also referred as the mIP2 or mIP2 promoter.

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.
