Lyophilized peptides are stable at room temperature for weeks. Upon arrival, always store lyophilized peptides in a freezer at - 20°C for maximum stability. For short-term storage, it is recommended to store peptides at 4°C.
Lyophilized peptides are often hydroscopic. For best results, maintain product for synthetic peptide in a dry environment. When preparing peptides for use or peptide antigen design for example, allow to equilibrate to room temperature before opening the container, reseal the vial quickly after weighing out desired quantity.
