inIs181 [ida-1p::GFP]. inIs182 [ida-1p::GFP]. This is a strain in which two integrated copies of the same construct were crossed into a single strain in order to have stronger expression. Both arrays contain pTZ3i, which is ida-1::GFP with 2.4 kb of ida-1 promoter driving expression of ida-1::GFP fusion proten with ida-1 introns 3-9 included.
