Storage and Handling Fundamentals

Proper storage is critical for maintaining peptide integrity. Here's what every researcher needs to know. Optimal Storage: - Temperature: -20°C (freezer) - Protection: Keep in original sealed vial - Light: Store in dark or opaque container - Humidity: Keep desiccant packet if included Shelf Life: Most lyophilized peptides remain stable for 2+ years when stored properly. Optimal Storage: - Temperature: 2-8°C (refrigerator) - Container: Original vial, upright position - Handling: Use sterile technique Typical Stability: 2-4 weeks depending on the peptide Normal Variations: - Slight color variation between batches - Loose powder that moves in vial - Small cake or pellet at bottom Potential Concerns: - Visible moisture or wetness - Large clumps or unusual texture - Strong unexpected odor - Cloudy solution after reconstitution Peptides arrive with cold packs to maintain temperature. Upon arrival: 1. Inspect packaging for damage 2. Check temperature indicator if included 3. Tr
