Introduction

Proper storage and handling are essential to preserve peptide integrity and reproducibility in research. This guide summarizes best practices from receipt through long-term use.

Upon Receipt

Verify packaging is intact, label matches order, and CoA is present. Record lot number and date in inventory logs.

If shipping on ice or dry ice, transfer immediately to recommended storage (2–8 °C or −20 °C depending on state).

Lyophilized Peptides

Stable at room temperature for short periods but best stored dry at 2–8 °C, protected from light and moisture.

For long-term storage (>6 months), −20 °C is recommended.

Reconstitution

Use bacteriostatic sterile water, PBS, or assay-compatible buffers. Avoid repeated freeze–thaw cycles by preparing aliquots.

If solubility is poor, pre-wet with a minimal amount of DMSO or acetic acid before dilution.

Aliquoting & Handling

Divide reconstituted stock into single-use vials. Label clearly with concentration, solvent, and date.

Use low-bind plastics to minimize adsorption. Work on ice where stability is temperature-sensitive.

Stability Considerations

Monitor for degradation such as oxidation (Met, Trp) or deamidation (Asn, Gln). Avoid light exposure for photosensitive sequences.

Add stabilizers (e.g., carrier protein, antioxidants) only if compatible with downstream assays.

Documentation

Maintain SOPs for storage and handling. Note freeze–thaw cycles, reconstitution details, and storage duration in lab notebooks.

Conclusion

Consistent handling reduces variability and preserves peptide quality. Standardizing protocols across labs improves comparability of results.
