Diagnostic reagents tend to be reactive in nature, which of course is what makes them useful, but it also means it can be challenging to stabilize them sufficiently to endow them with a long enough shelf life for commercial use. Even though lyophilization (freeze-drying) may be considered a relatively gentle drying process, there are still risks and pitfalls when applying it to diagnostic reagents. Further to this, the selection of any stabilizers must take into account the compatibility with the final assay as well as with the lyophilization process itself. This webinar will explore various aspects of formulation and cycle development for diagnostic reagents, including the selection of container-closure systems, which can be critical to long term stability, not least for those reagents that are used in such small quantities that the uptake of even small amounts of moisture during storage can represent a relatively large proportion of the sample mass and thus accelerate degradation of the final product.
