Desiccant
A desiccant is a hygroscopic substance — most commonly silica gel — that absorbs moisture from the surrounding environment. Desiccant packets are included with lyophilized peptide vials to maintain a dry microenvironment.
Moisture is one of the primary degradation pathways for lyophilized peptides. Absorption of water can lead to hydrolysis of peptide bonds, deamidation of asparagine and glutamine residues, and loss of the porous lyophilized structure. Keeping vials sealed with desiccant present minimizes these risks during long-term storage.

Lyophilization
Freeze-drying — a dehydration process that removes water from a frozen peptide solution under vacuum, producing a stable dry powder.
Shelf Life
The duration a peptide product maintains acceptable quality when stored under specified conditions.
Oxidation
A chemical reaction adding oxygen to peptide residues, particularly methionine, cysteine, and tryptophan, leading to structural modification and loss of activity.
Vial
A small sealed glass or plastic container used to store lyophilized peptide powder, typically with a rubber septum and aluminum crimp cap.
