Secreted (renilla) luciferase

摘要

A polynucleotide encoding a secreted form of wild type Renilla luciferase. Also provided is a polynucleotide encoding a secreted modified form of wild type Renilla luciferase. Additionally, the polypeptides encoded by the polynucleotides of the present invention and uses of the polynucleotides and polypeptides of the present invention in biological assays. Also, a stable mammalian packaging cell line which produces retroviruses carrying a polynucleotide encoding a secreted Renilla luciferase.
