AAV with CamKII(0.4) promoter driven EYFP

This AAV expresses EYFP 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 .

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
