Organizing shipping studies to evaluate the transferability of cell- and tissue-based test systems and reagents: An end user perspective.

Abstract

Cell- and tissue-based test systems and reagents (e,g., cells, tissues, organs, reconstructed tissue models, or cell/tissue culture reagents) are increasingly being used in regulatory and non-regulatory testing applications due to their ability to reflect human biology. These test systems and reagents may be shipped long distances, including across international borders, from the vendor to the testing laboratory. To ensure confidence in the data obtained from testing involving these systems and reagents, it is important for the testing laboratory to confirm that quality is maintained during the shipping process and that the materials can be used for their intended application (i.e., that the test method associated with the test system and/or reagent can be effectively transferred between laboratories). This paper describes various types of shipping studies that might be conducted when transferring a method to a new laboratory and key considerations for their design that can help maintain the quality of the test systems and reagents during the shipment process. Furthermore, emphasis is placed on the need for good communication between vendors, shipping agents, and end users to ensure efficient transferability of test methods.
