Preserving peptide integrity by freeze-drying
Following purification by HPLC, peptide solutions are typically freeze‑dried to remove solvents, a process that preserves structural integrity and biological activity while minimizing aggregation. Samples are processed in beaker flasks to facilitate easy collection and reduce product loss. The resulting lyophilized material is consistently obtained as a fine, fluffy powder without collapse or stickiness, ensuring physical stability suitable for long‑term storage and downstream therapeutic or research applications
Stabilizing oligonucleotides for long-term storage by freeze-drying
Freeze-drying preserves their integrity and extends shelf life of Oligonucleotides, short DNA or RNA sequences. Using the Lyovapor™ L-250, 50 mL Falcon tube samples were rapidly frozen in liquid nitrogen and dried in a 12-port manifold at 0.1 mbar, producing stable pellets in 16 hours. Multiple trials showed reproducible results, demonstrating reliable vacuum control, and effective vapor trapping.
Freeze-dried Okra Vegetable
Okra (Abelmoschus esculentus), due to its high moisture content and sensitive structure, is difficult to dehydrate using conventional drying techniques. This application note evaluates the freeze-drying of okra using the Lyovapor™ L-210 freeze-dryer. The low-temperature, low-pressure drying process enables efficient moisture removal by sublimation, resulting in dried okra with low residual moisture and well-preserved structure and appearance. The high-quality freeze-dried okra can stored safely and used for functional food applications
