Why Measure Apoptosis?
Apoptosis is a critical regulator of tissue homeostasis in both normal and pathological cellular responses. Dysregulation of apoptotic pathways is implicated in cancer, autoimmune disorders, neurological diseases, infectious diseases and many other conditions.
Quantitative assessment of apoptosis enables researchers to:
- Evaluate compound-induced cell death
- Characterize therapeutic mechanisms of action
- Investigate cellular toxicity profiles
- Identify biomarkers associated with treatment response
- Support lead optimization and candidate selection
- Validate efficacy in advanced in vitro models
Our apoptosis testing platform combines multiple orthogonal approaches to provide robust and reproducible data for both exploratory and regulatory-focused studies.
Our Cell Apoptosis Assay Services
Assay Portfolio
Annexin V / PI Apoptosis Assay
A widely used method for distinguishing viable, early apoptotic, late apoptotic, and necrotic cells. This assay provides rapid and quantitative assessment of apoptosis and is suitable for a broad range of cell types.
Key Readouts
- Viable cells
- Early or late apoptotic cells
- Necrotic cells
- Total apoptotic population
Caspase Activity Assays
Caspase activation is a hallmark of programmed cell death. We offer sensitive assays for evaluating key apoptotic caspases involved in both intrinsic and extrinsic pathways.
Key Readouts
- Caspase-3/7 activation
- Caspase-8 activation
- Caspase-9 activation
- Relative apoptosis activity
TUNEL Assay
TUNEL assays detect DNA fragmentation associated with late-stage apoptosis and are suitable for cultured cells, organoids, and tissue samples.
Key Readouts
- DNA fragmentation
- Apoptotic nuclei
- Quantitative apoptosis measurements
Mitochondrial Membrane Potential Assays
Measures early intrinsic apoptosis events via changes in mitochondrial membrane potential, valuable for assessing mitochondrial dysfunction and apoptosis‑related toxicity.
Key Readouts
- Mitochondrial depolarization
- Membrane potential changes
