A Rapid Protocol for Integrating Extrachromosomal Arrays With High Transmission Rate into the C. elegans Genome

Overview

This protocol describes a rapid and low material consuming procedure for the integration of transgenic extrachromosomal arrays into the Caenorhabditis elegans genome using ultraviolet (UV) irradiation. This method is particularly effective for transgenic lines that transmit extrachromosomal arrays at a high rate.
