Standard Guide for Cell Culture Growth Assessment of Single-Use Material

Importancia y uso:

5.1 A risk-based approach must be used to determine the cell lines, test articles, and materials used for testing. An evaluation of relevant factors should be made to determine if a test article is representative of the intended use.

5.2 Cell culture compatibility should be assessed if the material is in direct contact with cell culture medium regardless of duration of contact. Test articles can be of a single material or assembled from a multitude of materials.

5.3 Two perspectives to single-use material cell culture compatibility assessments are the supplier and the end user perspectives. It is understood that the supplier may have better access to single-use materials and material manufacturing processes, while having limited access to representative cell lines. Supplier assessment of materials are best tested using cell lines available that have shown known material sensitivity. The end users may have more limited access to materials but access to more representative cell lines and processes. Therefore assessment of compatibility of material with a specific cell line in a process is best evaluated by the end user.

5.4 This guide outlines best practices to establish test procedures. Appendix X1 outlines an example test procedure for a commercially available CHO cell line.
