Summary

Automatic Translation

Da GPCR'er er attraktive mål for lægemidler, er GPCR ligandscreening således nødvendig for identifikation af blyforbindelser og for undersøgelser af forældreløs eller sjældne børn. Mod disse bestræbelser, beskriver vi PRESTO-Tango, en open source ressource platform, der anvendes til samtidig profilering af forbigående β-arrestin2 rekruttering på ca 300 GPCRs ved hjælp af en TEV-baseret reporter assay.
