Peptide Storage
Correct storage is fundamental to maintaining the integrity of peptides over time. At Neuroceptix Labs, we guide specific conditions to ensure maximum stability, preventing degradation, oxidation, or loss of activity of the compounds.
How to store lyophilized peptides
Peptides in lyophilized form can withstand long-term storage when kept under ideal conditions:
-
Recommended temperature: –20°C or lower.
-
Dry and dark environment: avoid exposure to light and humidity.
-
Hermetically sealed vial: prevents moisture absorption and contamination.
-
Long-term stability: under ideal conditions, the material can maintain its integrity for months or even years.
These conditions ensure that the peptide remains stable until reconstitution, preserving its purity and original structure.
Precautions when opening the vial
When handling the product:
-
Allow the vial to reach room temperature before opening — this prevents internal condensation and moisture absorption.
-
Use gloves and sterilized materials to avoid contamination.
-
Avoid opening the vial repeatedly: always remove the required amount and close it immediately.
After reconstitution: storage of the solution
Reconstituted peptides become more sensitive. To maintain stability:
-
Ideal temperature: 2–8°C (refrigeration).
-
Protection from light and oxygen: store in amber or opaque vials.
-
Use within an appropriate timeframe: it is recommended to use the solution within 7 to 30 days (depending on the compound).
-
Avoid repeated freeze–thaw cycles: each cycle may degrade the molecule.
-
If long-term storage is required, divide into aliquots and freeze each one separately.
Factors that affect stability
The integrity of peptides can be compromised by:
-
Exposure to high temperatures
-
Humidity or condensation
-
UV light or continuous direct light
-
Inadequate solvent pH
-
Microbial contamination or contamination from impure solvents
Therefore, the precautions mentioned are essential to keep the compound reliable and effective for research purposes.
Shelf life and traceability
Each Neuroceptix batch comes with detailed technical documentation, including:
-
Manufacturing date and expiration date
-
Batch number
-
Recommended storage conditions
-
Technical instructions for reconstitution and storage
This traceability ensures transparency and trust, which are essential for laboratories and researchers that require scientific rigor.
