ASTM E1262

ASTM E1262 is the ASTM standard guide for the performance of the Chinese Hamster Ovary cell/Hypoxanthine Guanine Phosphoribosyl Transferase gene mutation assay. It provides a technical framework for evaluating how this assay is carried out and interpreted, helping users apply a consistent approach to mutagenicity assessment. For laboratories and quality-focused organizations, it supports more reliable testing practices, clearer communication of results, and better alignment with established ASTM guidance.

Overview of ASTM E1262

This standard guide focuses on the performance of a CHO/HGPRT gene mutation assay, a commonly referenced biological test used in genetic toxicology work. ASTM E1262 is intended to guide how the assay is performed so that results are more consistent and technically comparable across testing programs. It is most relevant where controlled laboratory methods, documented procedures, and dependable interpretation of mutation data are important for screening or evaluation purposes.

Common use cases of ASTM E1262

ASTM E1262 is commonly used in laboratory settings that perform in vitro mutation testing with Chinese hamster ovary cells and HGPRT-based endpoints. It may be applied during method development, routine assay execution, internal quality control, or when comparing test outcomes across studies. The standard is also useful for teams that need a shared reference for assay performance expectations, especially in regulated or documentation-heavy environments where consistency matters.

Benefits of using ASTM E1262

Using ASTM E1262 can help improve consistency in assay performance and support more dependable test results. It is useful for establishing a common technical basis for procurement, validation, reporting, and quality control activities related to the CHO/HGPRT gene mutation assay. For organizations evaluating mutagenicity-related data, the standard may also help reduce variability, strengthen repeatability, and support more confident compliance with internal or external testing requirements.
