Photoprotein aequorin: use as a reporter enzyme in studying gene expression in mammalian cells.


Aequorin is a luminescent protein present in the jellyfish Aequoria victoria which emits light (at 460 nm) in the presence of Ca2+. We report here that aequorin can be used as a reporter enzyme to monitor gene expression in eukaryotic cells. A cDNA encoding apoaequorin was fused to several eukaryotic promoters, including those of SV40, RSV and the HSV-1 tk… (More)
