The Essential Guide to Safety, Storage, and Handling Of Peptides

Peptides, having divergent roles in biology and the potential in therapeutic applications, have garnered compelling interest recently. As researchers and scientists have paced up working with these powerful biomolecules, it becomes vital to understand the safety, storage, and handling of peptides. This blog post from the author aero will provide a comprehensive guide on how to maintain the peptide integrity and how you can ensure the effectiveness of peptides in different applications.

Importance of proper handling of peptides

Peptides are too sensitive to a number of factors, that includes temperature, light, and moisture. Inappropriate handling of peptides can often lead to the peptide degradation, reduced bioactivity, and eventually compromised experimental results. To avert these issues and to ensure the reliability of your research, it becomes vital to follow appropriate guidelines for the safety, storage, and handling of peptides.

Storage of Peptides: Maintaining Peptide Stability

Proper storage is a no-brainer and pivotal to safeguard the quality of peptide and to prevent degradation of peptides. The following practices should be observed to ensure peptide stability:

  1. Temperature: You should always store peptides at -200 C or below. As it has been seen that lower temperature minimizes the risk of the degradation of peptides. This degradation is often the result of hydrolysis, oxidation, or any other chemical reactions.
  2. Desiccation: Always ensure that the peptides are stored in a dry environment to prevent degradation induced by moisture. Always use desiccant packs or a vacuum-sealed container to maintain drier conditions.
  3. Protection from Light: Peptides, specifically those containing photosensitive amino acids such as tryptophan, cysteine, and methionine, must be protected from light to prevent photodegradation. Always store peptides in opaque or amber-colored vials.

Handling of peptides: Ensuring the quality and purity of peptides

To maintain peptide quality and purity, follow these guidelines when handling peptides:

  1. Aseptic techniques: Always use gloves, clean equipment, and aseptic techniques when working with peptides to prevent contamination.
  2. Solubilization: You should ensure that you are choosing an appropriate solvent for dissolving peptides. Always take  the peptide’s solubility, stability, and intended application into consideration. Common solvents include water, dimethyl sulfoxide (DMSO), and acetonitrile.
  3. Weighing: When you are weighing peptides, always use a microbalance for accurate measurements and handle the peptide with utmost care to avoid loss of material or contamination.
  4. Dilution: Always prepare peptide solutions at the perfect concentration by diluting the stock solution with an appropriate solvent or buffer.

Safety considerations in peptide handling

To ensure the safe handling of peptides, adhere to the following guidelines:

  1. Material Safety Data-Sheet (MSDS): Familiarize yourself with the MSDS for each peptide you are using for your research, which provides information on hazards, precautions, and emergency procedures.
  2. Personal Protective Equipment (PPE): Always wear suitable PPE kit prior to your research that includes gloves, lab coats, and sunglasses (face mask), to prevent exposing yourself to potentially harmful properties.
  3. Ventilation: Always carry on your research in a well-ventilated area or under a fume hood.
  4. Disposal: Always dispose of peptide waste and contaminated materials according to local regulations and guidelines provided in the MSDS.

Frequently asked questions on safety, storage, and handling of peptides

How long can peptides be stored without degradation?
The stability of peptides differs and it depends on their sequence, composition, and storage conditions. With proper safety, storage, and handling of peptides, a majority of them can be stored for several months to years at -20°C or below without significant degradation.

Can peptides be stored at room temperature?
A few peptides may survive short-term storage at room temperature without significant degradation, but we will not recommend this. In order to ensure the longevity, stability, and the quality of the peptides, the ideal condition is to store them at -20°C or below.

How do I know if my peptides has been degraded?
Degradation of peptides can be obvious in a number of ways that includes changes in appearance, solubility, or biological behavior. In order to assess the quality of the peptides, you can always perform analysis by using techniques like Mass Spectrometry, High Performance Liquid Chromatography (HPLC), or functional assays relevant to your research.

Can I refreeze peptides after thawing?
Repeated freeze-thaw cycles can be a major cause of the degradation of peptides. As in this case, ice crystals are formed, which can disrupt peptide structure. To minimize this risk, it is always recommended to aliquot your peptides into much smaller volumes and store them distinctively. This way, you can thaw only the required amount for each experiment, minimizing the need for refreezing.


To conclude, it would be safe to say that understanding and implementing proper safety, storage, and handling of peptides is vital for maintaining peptide quality. This paves the path for the accurate research results and also averts potential hazards. If you follow the above guidelines, it is highly possible that your peptides will remain stable, pure, and ready for use in a number of applications.
