Description and Uses
Description

Mi{24xMS2-SL} 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 a '24xMS2-SL' stem-loop cassette that contains 24 copies of Tag:MS2 (the cassette contains 12 tandem repeats of a sequence encoding 2 unique Tag:MS2 stem loops separated by a short linker, and the version of the stem loops used were originally optimized for stable expression in bacteria). Insertion of the Mi{24xMS2-SL} cassette in the correct orientation into an intron of a gene of interest allows visualization of nascent transcription of that gene; the Tag:MS2 sequences in the nascent transcript form stem loops that can be detected by a reporter protein that includes Tag:MCP (which binds Tag:MS2).
