A secreted luciferase for ex vivo monitoring of in vivo processes
Luciferases are widely used to monitor biological processes. Here we describe the naturally secreted Gaussia princeps luciferase (Gluc) as a highly sensitive reporter for quantitative assessment of cells in vivo by measuring its concentration in blood. The Gluc blood assay complements in vivo bioluminescence imaging, which has the ability to localize the signal and provides a multifaceted assessment of cell viability, proliferation and location in experimental disease and therapy models.
AFP - At least 18 people were killed and 22 injured on Saturday when dozens of homes in northern Cairo collapsed after being hit by a massive rockslide, Egyptian emergency services said.
