Viral and Bacteriophage Stabilization: Stabilizes virions and phage particles during freezing, thawing, and storage (e.g., −80°C or lyophilization) to preserve infectivity.

Transport Medium for Obligate Intracellular Bacteria: Maintains viability of clinical and research specimens containing Chlamydia trachomatis, Chlamydia pneumoniae, Rickettsia rickettsii, and Coxiella burnetii.

Virus/Phage Titration and Dilution Buffer: Used as a stabilizing diluent for plaque assays and serial dilutions to minimize titer loss.

Storage of Chlamydial Elementary Bodies: Preserves infectivity of purified elementary bodies for culture, passage, and quantification assays.

Resuspension and Washing Buffer: Protects labile viral particles and sensitive bacteria during pelleting, resuspension, and washing steps.

Lyophilization Excipient: Serves as a protective matrix for freeze-drying viral stocks and reference materials.
