Here, we present detailed protocols for solid-state amide hydrogen/deuterium exchange mass spectrometry (ssHDX-MS) and solid-state photolytic labeling mass spectrometry (ssPL-MS) for proteins in solid powders. The methods provide high-resolution information on protein conformation and interactions in the amorphous solid-state, which may be useful in formulation design.

The tissue-specific extracellular matrix (ECM) is a key mediator of cell function. This article describes methods for synthesizing pure ECM-derived foams and microcarriers that are stable in culture without the need for chemical crosslinking for applications in advanced 3D in vitro cell culture models or as pro-regenerative bioscaffolds.
FAQs
Secondary drying is important because it removes moisture that remains after primary ice removal. In lyophilized immunology and infection materials, controlling this residual water supports preservation of activity during storage rather than stopping once visible ice has sublimated. This stage therefore contributes to the stability and usable lifetime of vaccines, antibodies, diagnostic reagents, and microbial preparations.
Reduced pressure enables frozen water to leave the sample as vapor, helping avoid a liquid-water phase during the main drying step. That physical pathway matters because the method is intended to maintain the material’s structure and activity. For infection research, preserving those properties can support more consistent handling and results after storage.
Compared with relying only on refrigeration, lyophilization offers a preservation strategy that can reduce dependence on continuous cold storage. Its value is logistical as well as biological: stabilized materials may be easier to transport and handle, while laboratories working with temperature-sensitive vaccines, antibodies, or diagnostic reagents can maintain access across settings where refrigeration is less practical.
A lyophilization cycle coordinates freezing, vacuum-driven primary drying, and secondary drying in that order. Freezing prepares the material for ice removal; reduced pressure then supports sublimation, and the final stage removes residual moisture. Keeping these stages distinct helps preserve structure and activity, which is central when preparing sensitive immunological or infectious materials for storage.
Within immunology and infection research, the approach can support preservation of vaccines, antibodies, diagnostic reagents, and microbial preparations. These materials differ in purpose, but they share a need for storage stability and dependable activity. Using one preservation strategy across these categories can simplify handling and support their transport, laboratory use, and clinical applications.
By reducing degradation during storage, lyophilization can help laboratories obtain more consistent results from temperature-sensitive materials. The benefit extends beyond preservation: easier handling and transport may expand access to vaccines, antibodies, diagnostic reagents, and microbial preparations. In immunology and infection research, these logistical gains can support both laboratory studies and clinical applications without relying solely on refrigeration.
