The chromium (51Cr) release assay has been widely used for viability measurements, even though it has major disadvantages such as high manual workload and poor time resolution. By the use of LigandTracer, 51Cr release viability measurements on adherent cells can be significantly simplified and improved. LigandTracer enables a time-resolved detection of 51Cr in target cells, with the result that the effect of toxic material is updated continuously throughout the experiment. Here we explain the principle behind this novel real-time viability assay and show viability curves for known toxic compounds on A431 and U343MGaCl2:6 cell lines.
