Humanized TagCFP TagCFP codon usage is optimized for high expression in mammalian cells [Haas et al., 1996], but it can be successfully expressed in many other heterological systems. pTagCFP-C FP111
pTagCFP-N FP112
TagCFP-actin fusion Human β-actin is fused to the TagCFP C-terminus. When expressed in mammalian cells, this fusion provides cyan fluorescent labeling of β-actin in living cells. pTagCFP-actin FP114
TagCFP-mito fusion A mitochondrial targeting sequence (MTS) is fused to the TagCFP N-terminus. MTS was derived from the subunit VIII of human cytochrome C oxidase [Rizzuto et al., 1989; Rizzuto et al., 1995]. When expressed in mammalian cells, this variant provides cyan fluorescent labeling of mitochondria. pTagCFP-mito FP117
