In Vitro Mammalian Cell Gene Mutation Testing OECD 476 Validation Method Development Test
The In Vitro Mammalian Cell Gene Mutation Test (OECD 476) is a pivotal regulatory test designed to assess the potential of chemical substances, pharmaceuticals, and other agents to cause gene mutations in mammalian cells. This method provides critical information for understanding the mutagenic properties of compounds under development or already on the market. Employing this approach ensures that new drugs and chemicals are safe from genotoxic risks, a cornerstone in regulatory compliance.
The test is conducted using Chinese hamster ovary (CHO) cells or V79 cells, which have been widely accepted for their stability and reliability in genetic tests. The OECD 476 method evaluates the ability of mutagens to cause point mutations by measuring the frequency of spontaneous and induced frameshift mutations. This process involves a series of steps that are meticulously designed to assess the genotoxic potential of test substances.
The test is particularly relevant for pharmaceuticals, where the focus on patient safety and regulatory approval necessitates rigorous evaluation methods. Pharmaceutical companies often require this testing as part of their drug development process to ensure compliance with international standards such as OECD guidelines and ICH Q2B recommendations.
Our laboratory specializes in providing comprehensive validation services for the OECD 476 method, ensuring that clients receive accurate and reliable results. Our expertise lies in method development, optimization, and full validation services, which are critical to achieving regulatory acceptance of testing protocols.

Scope and Methodology
The OECD 476 In Vitro Mammalian Cell Gene Mutation Test is designed to assess the ability of a chemical substance to induce heritable mutations in mammalian cells. The test focuses on the induction of frameshift mutations, which can lead to genetic instability and potential health risks if not properly managed.
The methodology involves several key stages:
- Cell Preparation: Cultivation of V79 or CHO cells under specific conditions
- Treatment with Mutagen: Exposure of the cells to the test substance for a defined period
- DNA Repair Assessment: Evaluation of DNA repair mechanisms in response to the mutagen
- Mutation Frequency Measurement: Determination and statistical analysis of mutation frequencies
The test is conducted under controlled conditions to ensure consistency and reliability. The choice of cells, duration of treatment, and conditions for DNA repair are critical factors that must be carefully considered and standardized.
