简介：
Overview
This cell-based assay is designed to identify and characterize molecules that can stimulate or inhibit G protein-coupled receptor-mediated intracellular calcium mobilization. It allows for the screening of agents that interact with CXC chemokine receptor 4 (CXCR4) and can modify receptor-mediated intracellular calcium release.
