AAV with ELA1 promoter driven Venus

This AAV expresses Venus 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.

Like mCitrine and EYFP, Venus was developed in an effort to get better variants of YFP in terms of brightness and photo-stability. Venus has an Excitation/Emission spectrum of 515nm/529nm which is almost identical to that of EYFP and mCitrine.
