AAV with CamKII(0.4) promoter driven mCitrine

This AAV expresses mCitrine driven by a neuron CamKII(0.4) promoter.

This 0.4 Kb promoter is derived from murine α-Calcium/calmodulin-dependent kinase II (CaMKII), a gene with expression restricted to excitatory neurons in the neocortex and hippocampus. It was shown that the promoter activity of CaMKII(0.4) is almost identical to that of CaMKII(1.3) in cortical neurons, Compared to CaMKII(1.3), this short promoter allows cloning of longer gene of interest into the AAV construct .

mCitrine, like Venus, is derived from YFP, with increased brightness and stability. mCitrine has an Excitation/Emission spectrum of 516nm/529nm which is almost identical to that of EYFP, Venus and Topaz.
