mCherry is a member of the monomeric red fluorescent protein (mRFP) mFruits family, derived from DsRed of the Discosoma sea anemone. mCherry is a fluorescent protein chromophore used as a tool to visualize genes and analyze their function in experiments. mCherry absorbs light in the range of 540-590 nm and emits light in the range of 550-650 nm. Luciferase is an oxidase that produces bioluminescence and is widely used in biotechnology as a reporter gene. Unlike fluorescent proteins, luciferase does not require an external light source, but requires the addition of the substrate luciferin. This product is designed as a tool for the delivery and expression of mCherry-Luciferase mRNA for research. The product leverages the lipid nanoparticle (LNP) technology platform for simple and efficient delivery of mCherry-Luciferase mRNA to a variety of mammalian cells in vitro and in vivo. The LNPs used are formulated with SM-102, DSPC, cholesterol and DMG-PEG2000 at an optimal molar concentration for a high rate of encapsulation and efficient mRNA delivery. The sequence of the mCherry-Luciferase fusion protein consists of mCherry (236 amino acids) and Luc 550 amino acids) with a GS peptide linker (GGGGSGGGGSGGGGS) between them. The GenPept accession number for mCherry is WIO52923 and the GenPept accession number for Luc is AAA89088.
