AAV with ELA1 promoter driven EYFP

This AAV expresses EYFP driven by a pancreatic acinar ELA1 promoter.

Rat elastase 1 (Ela1; ELAI1; RATELAI1), also called chymotrypsin-like elastase family, member 1, is the major protease with elastin-degrading activity in the mammalian exocrine pancreas. The ELA1 promoter (0.3Kb) is comprised of the core promoter and enhancer, and directs transgene expression in pancreatic acinar cells, stomach, duodenum, and colon.

YFP is the longest wavelength-emitting variants of Aequorea GFP. The enhanced version, EYFP, has become one of the brightest and most widely utilized of the fluorescent proteins with an Excitation/Emission spectrum centered around 514nm/527nm. Other fluorescent proteins with similar emission spectrums include Topaz, Venus, Citrine and mCitrine
