WebBut how does it work, and what is it used for? S... Optogenetics let scientists literally control the brain, by controlling the signaling of individual neurons. WebIf the canonical Wnt signaling is activated, beta-catenin will translocate to the nucleus to associate with TCF/LEF transcription factors to activate transcription of Wnt target genes. Since this is a luciferase plasmid, you should see an increase in relative luciferase activity when substrate is added.

WebWhen these viruses co-infect a cell they form concatemers, are spliced together, and the full-length transgene can then be expressed. This method allows for longer transgene expression, but expression is much less efficient than with a single AAV virus (∼5%). Another technique for increasing packaging capacity depends on homologous … WebOptogenetics in neural systems - Yizhar et al., Neuron 2011 Transgenesis works instead by generating an animal that carries the opsin (or any other gene) in its DNA. This can be done in various way, such as by microinjection of embryonic stem cells carrying the transgene.
