490 BioTech is excited to announce we have increased the brightness of our LiveLight™ Toxicity Assay Kit. Single cells can now be identified and assayed using our simple, one-step, transfect-and-read format. This provides a convenient and reliable way to continuously monitor the viability or metabolic activity dynamics of cells for up to a week or more without any interaction or luciferin treatment required. Single HEK293 cells treated with LiveLight™ Toxicity assay mix were observed using CCD-camera-based high content imaging. Individual wells were continuously monitored for a full week. Visit 490 BioTech’s LiveLight™ product page to get a free sample and take advantage of this improvement today.
