Lyophilised peptides and reference standards are sensitive to heat, light and moisture. Good cold-chain practice keeps them stable from our facility to your bench.
Storage
Most lyophilised standards are best stored at -20°C, protected from light and kept desiccated.
Transit
Temperature-controlled packaging maintains conditions during transit, with insulation sized to the destination and season.
On arrival
Inspect, log, and return material to cold storage promptly to preserve the specified purity.
