Thermo Fisher Scientific offers an array of imaging reagents and kits to detect cells undergoing apoptosis. Select from a wide variety of caspase activity assays, DNA fragmentation and TUNEL assays, annexin V staining reagents and mitochondrial assays.

Accurate apoptosis analysis in your imaging assays

Many different approaches are used in the study of programmed cell death, or apoptosis. Cell death cascades are complex and dynamic, underscoring the importance of a multi-parametric approach for accurate assessment. Understanding the mechanisms of cell death and survival can represent a critical aspect of toxicological profiling and drug discovery. See our range of imaging assays to detect apoptotic cells undergoing processes ranging from caspase activation to phosphatidylserine translocation.
