Follow these protocols immediately upon receipt of your lyophilised peptide compounds to ensure compound integrity is maintained before any research activity begins.
Upon receipt, inspect the vial carefully. Lyophilised peptides may appear as a fine white powder, a translucent film, or may be effectively invisible inside the vial. The absence of visible material does not indicate a defective or empty product — this is entirely normal for high-purity lyophilised compounds.
Allow cold-shipped vials to reach full ambient room temperature before opening. Opening a cold vial in a warm environment causes condensation inside the vial, accelerating peptide degradation and moisture-induced aggregation. Allow a minimum of 30 minutes at room temperature before proceeding.
Open vials only in a clean, dry environment. Reseal immediately after each handling session to limit exposure to atmospheric humidity and oxygen — both accelerate peptide chain degradation. Where possible, work under a laminar flow hood using sterile technique throughout the entire session.
Reconstitution converts a lyophilised (freeze-dried) peptide back into a liquid solution for research use. Follow these steps in order to preserve compound purity and bioactivity.
Choosing the correct solvent is the most critical step in reconstitution. Always start with the mildest effective option. Bacteriostatic Water (BW) is the standard choice — its 0.9% benzyl alcohol content inhibits microbial growth and substantially extends usable shelf life of the reconstituted solution.
Using a sterile insulin syringe, introduce the solvent slowly by directing it along the inside glass wall of the vial — never inject it directly onto the lyophilised peptide. Slow side-wall addition prevents foaming and avoids mechanically disrupting the peptide structure.
Once the solvent is added, gently swirl the vial using a slow rolling motion between the palms. Do not vortex or shake vigorously. Mechanical agitation can denature sensitive peptide structures and significantly reduce bioactivity.
After adding the solvent and gently swirling, allow the vial to stand at room temperature for 15–30 minutes, swirling gently every few minutes. Most peptides will dissolve fully to produce a clear, colourless or very slightly tinted solution within this window.
If particles remain after 30 minutes, apply brief gentle sonication in a laboratory water bath sonicator (30–60 seconds). Persistent turbidity after this may indicate a solvent incompatibility — return to Step 1 and trial 0.1% acetic acid.
Correct storage is essential for preserving peptide potency and purity. Use these guidelines to maximise the working lifespan of your research compounds.
Additional guidance to protect the integrity of your peptide compounds at every stage of the research lifecycle.
Many peptides are photosensitive. Store in amber vials or wrap clear vials in foil. Minimise direct light exposure during handling — UV and fluorescent light can cleave peptide bonds and accelerate oxidative degradation.
Label all vials with: compound name, concentration (mcg/mL), preparation date, reconstitution solvent, and storage conditions. Missing labels are a leading cause of protocol errors and wasted compounds.
Repeated freezing and thawing is a primary cause of peptide degradation. Pre-aliquot all reconstituted peptides into single-use volumes before placing in the freezer. Once thawed, use within the refrigerated window.
Always use sterile, single-use syringes and needles. Wipe vial septa with 70% isopropyl alcohol before each insertion. Work in a clean environment and wear nitrile gloves to prevent cross-contamination.
