HTRF术语详解 详细 >>
FRET：指荧光共振能量转移，在供体和受体相互靠得很近时，光子能从一个受激发的荧光团（供体）转移到另一个荧光团（受体），并使后者发出荧光。
HTRF：均相时间分辨荧光，Homogeneous Time-Resolved Fluorescence ）是用来检测纯液相体系中待测物的一种常用方法。
背景（Background）：指在没有加入compound时检测到的信号值。
荧光受体（acceptor）：指在荧光团受到激光激发时，能发出特定波长的发射光的基团。HTRF®的能量受体均可为XL665和d2。

Monitoring Gq-coupled receptor response through inositol phosphate quantification with the IP-One assay

G-protein-coupled receptors (GPCRs) are transmembrane proteins that play a key role in the signal transduction of extracellular stimuli. GPCRs associate to a complex assembly of intracellular proteins regulating a large variety of signaling pathways. In particular, the production of inositol 1,4,5 triphosphate (IP3) signs the activation of Gq-coupled receptors. However, its very short half-life makes its assessment too challenging for drug screening operations and the monitoring of calcium release, triggered by IP3, has been extensively used as a downstream readout of this signaling pathway. Recently, a new homogeneous time-resolved fluorescence (HTRF) assay, detecting a downstream metabolite of IP3, inositol monophosphate (IP1), has overcome the drawbacks of the IP3 quantification, allowing its use in primary or secondary screening.
