Abstract
Optogenetics, that is, the use of photoswitchable/-activatable moieties to precisely control or monitor the activity of cells and genes at unprecedented spatiotemporal resolution, holds tremendous promise for a wide array of applications in fundamental and clinical research. To fully realize and harness this potential, the availability of gene transfer vehicles ("vectors") that are easily produced and that allow to deliver the essential components to desired target cells in an efficient manner is key. For in vivo applications, it is, moreover, important that these vectors exhibit a high degree of cell specificity in order to reduce the risk of adverse side effects in off-targets and to minimize manufacturing costs. Here, we describe a set of basic protocols for the cloning, production, purification, and quality control of a particular vector that can fulfill all these requirements, that is, recombinant adeno-associated viruses (AAV). The latter are very attractive owing to their apathogenicity, their compatibility with the lowest biosafety level 1 conditions, their occurrence in multiple natural variants with distinct properties, and their exceptional amenability to engineering of the viral capsid and genome. The specific procedures reported here complement alternative protocols for AAV production described by others and us before, and, together, should enable any laboratory to generate these vectors on a small-to-medium scale for ex vivo or in vivo expression of optogenetic elements.
