This page describes techniques that I have developed as a postdoc in Erik Jorgensen's lab at University of Utah. The techniques rely on the Mos1 transposon and allow you to insert transgenes into well-defined chromosomal locations (MosSCI) and to make targeted deletions near Mos1 elements (MosDEL). This website was set up with a description of the techniques in an effort to make them more accessible. I describe the most current Protocols, a FAQ about the techniques and links to where you can request reagents (Addgene and CGC).
