描述（Description）
The Human Activin RII (Luc) HEK293 Reporter Cell was engineered to express Smad signaling response element driving luciferase expressing systems. When stimulated with multiple ligands, including activin, myostatin and GDF-11, receptor-mediated signaling can drive Smad-mediated luminescence. Neutralization of biological effect of the ligand-receptor interaction by corresponding antibody results in a decrease in luminescence.
应用说明（Application）
• Screen for neutralizing antibodies blocking the ligand-receptor interaction.

背景（Background）
Actvin and myostatin bind to activin type II receptors (ActRIIA and ActRIIB), and the glycine–serine-rich domains of type I receptors are phosphorylated by type II receptors. Activin enhances follicle-stimulating hormone biosynthesis and secretion and is involved in apoptosis, fibrosis, inflammation, and neurogenesis.
