Mi{PT-spGFP11x7.1} represents a transgenic construct generated in vivo by using phiC31:int-mediated recombination to replace the attP cassette of a Mi{MIC} element insertion with an intron phase 1 protein trap cassette that is composed of a splice acceptor site, a (GGS)[[4]] flexible linker, seven tandem copies of the spGFP11 split fluorescent protein fragment (each copy separated by a flexible linker), another (GGS)[[4]] flexible linker and a splice donor site.
