The peptides are delivered in the form of a lyophilized powder. Short-term temperature fluctuations will not affect the quality and performance of products during their transport. At room temperature, the peptides are in lyophilized form stable for several weeks. We recommend that lyophilized peptides be stored in a freezer at -20 ºC. The overwhelming majority of the lyophilisates can be stable at this temperature for several years. It is advisable to avoid frequent repetition of the freezing and thawing process of the peptides.
