Abstract:
Here, we describe a highly efficient, medium-throughput strategy for cloning and in vivo screening of putative enhancers using the chick embryo. By incorporating 48 unique nanotags for use in NanoString nCounter® across three different fluorescent reporters and developing a rapid and efficient digestion/ligation type IIs restriction enzyme-based cloning protocol, we develop a multiplexed approach for rapidly identifying enhancer activity. For complete details on the use and execution of this protocol, please see Williams et al. (2019).
