    Abcam Rhod-4 Calcium Assay kit - Medium Removal No Wash (ab112156) is a fluorescence-based assay for detecting intracellular calcium mobilization. Cells expressing a GPCR of interest that signals through calcium are pre-loaded with Rhod-4 which can cross the cell membrane. Once inside the cell, the lipophilic blocking groups of Rhod-4 are cleaved by an esterase, resulting in a negatively charged fluorescent dye that stays inside the cell. Its fluorescence is greatly enhanced upon binding to calcium. When cells are stimulated with agonists, the receptor signals the release of intracellular calcium, which significantly increases the fluorescence of Rhod-4. The characteristics of its long wavelength, high sensitivity, and >250 times fluorescence enhancement make Rhod-4 the brightest red calcium indicator available in the marker, and it is an ideal tool for the measurement of cellular calcium through HTS screening. Compared to Fluo-8, Rhod-4 is more photostable, making its fluorescence imaging more robust.

    ab112156 provides an optimized assay method for monitoring the G-protein-coupled receptors and calcium channels using HTS instrumentation. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format.

  • Carbachol Dose Response measured in HEK293 cells using Rhod-4 Medium Removal No Wash Calcium Assay kit and Rhod-2.

    HEK293 cells were incubated with 100 μL of the dye-loading solution using ab112156, or 100 μL of Rhod-2 solution (5 μM) for 1 hour at room temperature. Carbachol (25 μL/well) was added to achieve the final indicated concentrations. The EC50 of Rhod-4 is about 0.8 μM, and that for Rhod-2 about 0.7 μM.

レビューと Q&A

The product is designed for plate reader based experiments, unfortunately we do not have direct experiences using flow cytometry with the kit. The kit should work though using Ex/Em = 540/590nm. Reviewing the internet, it seems that it is possible to u...
