Comprehensive Cell Health Detection Solutions: Full Coverage of Cell Viability, Cytotoxicity and Apoptosis Analysis
05 Jun 2026
1. Core Concept of Cell Health Detection
Cell health status assessment serves as the fundamental and core experimental procedure in modern cell biology research, preclinical drug screening, and biosafety toxicity evaluation. Cell viability, cytotoxic response, and apoptotic progression are three pivotal indicators that directly reflect the physiological state and survival fate of cells. Accurate, rapid, and reproducible detection of these indicators is indispensable for compound toxicity assessment, anti-tumor drug screening, cellular culture condition optimization, and mechanistic exploration of cell death.
Currently, conventional cell detection methods possess distinct technical limitations due to varied detection principles. Single-index detection approaches fail to comprehensively characterize the real physiological state of cells, as different testing technologies target cell metabolism, cell membrane integrity, and apoptotic signaling pathways respectively. To address the diversified and high-precision detection demands of scientific researchers, ANT BIO PTE. LTD. has developed a full-spectrum cell health detection system covering cell viability, cytotoxicity, and apoptosis, enabling multi-dimensional, all-round, and high-sensitivity evaluation of cellular health status.
2. Research Frontiers & Significance of Cell Health Evaluation
2.1 Research Frontiers
With the rapid development of high-throughput drug screening, cell therapy, and molecular pharmacology research, traditional single-parameter cell detection can no longer meet the requirements of modern biomedical research. Current frontier research focuses onmulti-index combined detection, early subtle cell damage identification, ultra-low cell volume detection, and high-throughput automated screening. Researchers are committed to establishing a systematic cell health evaluation system to distinguish different cell death modes (apoptosis, necrosis, and metabolic dysfunction) and clarify the mechanism of drug-induced cellular damage.
In particular, early cytotoxicity identification and quantitative apoptotic signal analysis have become key technical bottlenecks in preclinical drug efficacy and safety evaluation. Upgraded luminescence and fluorescence detection technologies have gradually replaced traditional colorimetric methods, becoming the mainstream tools for high-sensitivity cell health detection in frontier research.
2.2 Research Significance
Systematic cell health detection is the core foundation for verifying drug efficacy, evaluating biosafety, and exploring cellular stress response mechanisms. Multi-dimensional detection of cell viability, cytotoxicity, and apoptosis can effectively avoid experimental deviation caused by single metabolic index detection, accurately distinguish reversible cell functional damage and irreversible cell death, and provide reliable quantitative data for drug screening, toxicological evaluation, and basic cell mechanism research. It also provides critical technical support for the research and development of anti-tumor drugs, targeted therapeutic agents, and cell-based biological products.

3.1 CyQuantiFluor™ Cell Viability Assay Kit (UA079047)
Traditional cell viability detection relying on cellular metabolic activity is easily interfered by culture conditions and drug treatment, resulting in inaccurate detection results. Different from conventional metabolic-dependent methods, this kit adopts a novel detection strategy to quantify viable cells by directly detecting intact cellular DNA content, completely eliminating metabolic fluctuation interference.
Detection Mechanism: The kit consists of a DNA-specific fluorescent dye and a background blocking dye. The DNA-binding dye emits weak fluorescence in a free state; after penetrating the intact cell membrane of viable cells and binding to nuclear DNA, its fluorescence intensity is significantly enhanced. The background blocking dye cannot penetrate viable cell membranes, which effectively shields the fluorescence signal of DNA released by dead cells and ensures specific detection of viable cells.
Product Advantages: Metabolism-independent detection ensures ultra-high result accuracy; homogeneous ready-to-use formulation realizes single-step sample addition and reduces operational errors; specific DNA binding design achieves high signal-to-noise ratio and excellent repeatability; fully adapted to high-throughput screening scenarios such as tumor cell proliferation detection and compound activity screening.
3.2 UA-Glo® Luminescent Cell Viability Assay Kit (UA070103)
ATP-based luminescence detection is the most widely recognized and authoritative method for cell viability analysis, serving as the gold standard for cell quantification in biomedical research. This kit quantifies viable cell numbers by detecting intracellular ATP content, with a strict linear correlation between ATP concentration and viable cell quantity.
Detection Mechanism: Intracellular ATP in viable cells acts as an essential substrate for the luciferase-catalyzed luciferin luminescence reaction. The luminescence intensity is positively correlated with ATP content, thus reflecting the number of viable cells accurately. ATP degrades rapidly after cell death, enabling precise monitoring of dynamic changes in viable cell populations.
Product Advantages & Applications: The kit features ultra-high sensitivity (detection limit: 100 cells/well) and excellent linearity (r²>0.999); the homogeneous one-step operation simplifies experimental procedures and minimizes manual errors; stable glow luminescence signal is suitable for large-scale high-throughput screening. It is widely applied in cell proliferation and cytotoxicity screening, drug sensitivity testing, and antibody-dependent cellular cytotoxicity (ADCC) evaluation.
3.3 UA-Glo® Fluorescent Cell Viability Assay Kit (UA079015)
This product targets early and subtle cellular functional damage that cannot be identified by conventional ATP detection methods, realizing advanced warning of cell health abnormalities based on intracellular specific protease activity.
Detection Mechanism: The detection target is a specific protease stably existing in viable cells. The protease can cleave polypeptide-fluorophore substrates to generate specific fluorescent signals. Once the cell membrane integrity is damaged, the protease loses activity, and the fluorescent signal disappears, realizing real-time monitoring of cell functional status.
Core Advantage: It has excellent multi-plex detection compatibility. Complementary to ATP luminescence detection technology, it can be combined with UA-Glo® luminescent viability assay and Caspase 3/7 apoptosis assay kits for synchronous detection, supporting in-depth research on cellular cytotoxicity mechanisms and multi-dimensional cell health analysis.
3.4 UA-Glo® LDH Luminescent Cytotoxicity Assay Kit (UA079041)
Lactate dehydrogenase (LDH) is a stable cytoplasmic enzyme that is released into the culture medium once the cell membrane is damaged. Traditional colorimetric LDH detection has low sensitivity and can only detect about 500 necrotic cells. This kit upgrades the traditional colorimetric system to a high-sensitivity enzymatic coupled luminescence system, breaking through the technical bottlenecks of conventional cytotoxicity detection.
Detection Mechanism: LDH in the culture supernatant catalyzes lactic acid oxidation and NAD⁺ reduction to generate NADH. The reduced enzyme further converts the substrate into luciferin, and luciferase catalyzes luciferin to produce a luminescent signal. The luminescence intensity is strictly proportional to LDH activity, realizing quantitative detection of cellular membrane damage and cytotoxicity.
Product Advantages: Ultra-high sensitivity enables detection of LDH release from fewer than 10 cells; only 2-5 μL of culture supernatant is required for detection; cell lysis-free operation allows continuous cell culture and dynamic monitoring; homogeneous one-step addition simplifies operation and adapts to 96-well, 384-well and 1536-well high-throughput screening platforms.
3.5 UA-Glo® Caspase 3/7 Cell Apoptosis Assay Kit (UA079012)
Caspase 3/7 are the executive key enzymes in the endogenous and exogenous apoptotic signaling pathways, and their activation marks the initiation of irreversible cellular apoptosis. This kit achieves precise quantitative evaluation of apoptosis levels by detecting intracellular Caspase 3/7 activity.
Detection Mechanism: The kit contains a specific substrate coupled with DEVD tetrapeptide sequence and aminoluciferin. The fluorescent signal is blocked when the substrate is intact. Active Caspase 3/7 specifically cleaves the DEVD sequence to release free aminoluciferin, which generates a stable bioluminescent signal under luciferase catalysis. The luminescence intensity is positively correlated with Caspase 3/7 activity and cellular apoptosis degree.
Product Advantages & Applications: The one-step "add-mix-detect" operation eliminates washing and medium replacement steps; low background luminescence ensures high sensitivity for early and low-level apoptosis detection; wide dynamic range adapts to samples with different apoptosis degrees. It is widely used in anti-tumor drug screening, cytotoxic mechanism research, and gene functional verification. Combined with viability detection, it can effectively distinguish cell death modes (apoptosis, necrosis, and metabolic failure).
