Storage
Storage: 5 articles from Peptides Info. Handling, storage and laboratory reference.
Cold Chain and Temperature Excursions: Transport, Receipt and Assessment Procedure
What ambient transit costs lyophilised material, and why a solution has no equivalent tolerance. Receipt recording, monitoring devices, cake appearance as thermal evidence, and a procedure for assessing an excursion.
Container Selection and Surface Adsorption: Materials, Closures and Peptide Lost to the Wall
Peptide bound to the container wall is routinely mistaken for low potency. Material comparison, closure selection, mitigation options and a procedure for detecting the loss.
Freeze–Thaw Cycles and Aliquoting: Damage Mechanisms and Sizing Practice
Freeze–thaw damage is applied by the transition, not by the cold. Reference on the physical stresses, the variables under control, and how to size aliquots so the question of cycle count never arises.
Stability of Peptides in Solution: Controlling Variables and Handling Practice
Solution-phase stability is a different problem from the dried solid, governed by different variables. Covers the pH trade-off, adsorptive loss to containers, and a single-use aliquot procedure.
Storage of Lyophilised Peptides: Conditions, Containment and Handling Procedure
Reference conditions for holding freeze-dried peptide material: temperature bands, moisture control, containment and light exclusion. Includes equilibration and receiving procedures.
