In Vitro Toxicology
Innovative Solutions for Early Safety Assessment

Mitigating Risk in Drug Development
Predictive toxicology is a pivotal aspect of modern drug development, utilizing advanced scientific techniques to foresee potential adverse effects of drug candidates. By leveraging in vitro, in silico, and in vivo approaches, predictive toxicology aims to provide early insights into the safety profile of drug candidates, enabling efficient decision-making in drug development. This proactive approach not only mitigates risks but also reduces the likelihood of late-stage failures, saving time and resources.
Enzo’s broad range of scientific expertise and industry-proven manufacturing capabilities provides a comprehensive set of solutions for predictive toxicology when determining genotoxicity, membrane integrity, autophagy, and oxidative stress. Our products are reliable, cost-effective, and compatible with high-throughput capabilities.
With over 45 years of experience and manufacturing excellence, Enzo’s overarching goal is to provide innovative tools that enhance the efficiency, cost-effectiveness, and overall success of drug development endeavors
Enzo’s products and services can help to streamline operations, making drug development more accessible and efficient.

DNA Damage ELISA kit
Exposure of cells to oxidative and environmental stresses frequently results in the breakdown or oxidation of genomic DNA. DNA Damage ELISA kit is a colorimetric solution to evaluate the integrity of genomic DNA, or to assess the presence of oxidized DNA and is frequently used as means of verifying the onset of apoptosis or DNA damage.
- Highly sensitive measurements, detecting as low as 1 ng/ml of 8-OHdG
- Also detects 8-hydroxyguanosine (product of oxidative RNA damage) and 8-hydroxyguanine (product of oxidative DNA damage by hydroxyl radicals)
- Reliable and validated in-house in a variety of sample matrices including serum, saliva, urine, plasma, cell lysates and DNA extract
