The FLIPR® Calcium 4 Assay Kit provides a fast, simple and reliable fluorescence-based assay for detecting changes in intracellular calcium.

• Maximises fluorescent signal by reducing cell wash artifacts
• Reduced well-to-well variability, improving assay quality (Z' factor) and reliability (CV %) of high-throughput screens
• Mix-and-read protocol accelerates assay workflow and increases throughput
• Superior signal-to-noise ratio facilitates confirmation of endogenous or transiently transfected receptor activity during assay development
• Pre-optimised and validated protocols for the FLIPR® Tetra and FlexStation® Systems ensure navigation to both routine and unconventional cell lines and targets

FLIPR® Calcium 4 Assay Kit contains a proprietary masking dye (Component A) with higher light extinction in the extracellular solution to significantly reduce background and increase signal window. It is more inert and reduces compound interference. Successful targets include calcium channels, chemokine receptors, and transiently transfected receptors.
