In this video, we demonstrate phiC31-mediated site-specific transgene integration in the Anopheles embryo via microinjection. This method helps introduce desired genes into a host system for research and industrial applications.
Protocol
1. Preparation of plasmids for the microinjection mix NOTE: The protocol illustrated here involves the use of two plasmids: an attB (attachment site derived from the host bacterium)-tagged donor plasmid carrying the transgene of interest, and a helper plasmid that expresses the φC31 integrase under the regulation of the Drosophila Hsp70 promoter. Purify donor and helper plasmids using an endo…
