Graphic showing the workflow of using a pooled AAV CRISPR library in vitro. Step A shows the AAV containing the library with either the gRNA only or gRNA plus Cas9 and infecting cells expressing Cas9 or wild-type. The different guides are represented by different colors in individual cells. Step B shows the results of the positive or negative selection, with only one type of guide (color) being chosen. Step C shows verification using next generation sequencing.
