Peptides are naturally occurring molecules in the human body, consisting of short chains of amino acids linked by peptide bonds. These molecules serve various biological roles and can be synthetically replicated to be identical to their endogenous (naturally occurring) counterparts. Synthetic peptides are used extensively in scientific and medical research to study biological processes and cellular pathways.

Researchers in disciplines such as biochemistry, molecular biology, and pharmacology use peptides to explore critical human functions, including; cell signalling, protein-protein interactions, receptor functions, and potential therapeutic applications. Endogenous peptides act as signalling molecules, binding to specific receptors to elicit physiological responses which regulate various bodily functions. Unsurprisingly, peptides have become key targets for drug development and therapeutic interventions.

Peptides are synthesized through a technique called solid-phase peptide synthesis (SPPS). Here's a simplified overview:

1. Initiating the process: The first amino acid is anchored to a solid resin, and its amino group is protected.
2. Adding amino acids: The protective group is removed, allowing the next amino acid to join. This forms a peptide bond between the two amino acids.
3. Repeating the steps: The process continues with one amino acid being added at a time, creating the peptide chain. The peptide chain is biologically capped at 30  bonded amino acids, after which a protein is formed.

Once the full peptide sequence is assembled, the peptide is cleaved from the solid resin using an acid to break the bond, which also removes any residual protective groups from the amino acids.This technique enables scientists to design peptides with tailored amino acid sequences, making them suitable for various applications in research, pharmaceuticals, and more.

How should peptides be handled and stored?

Peptides are highly hygroscopic, meaning they absorb moisture from the air. To prevent condensation, it's important to allow the peptide to reach room temperature before opening the container. A desiccator or dry box is the best option for warming peptides to avoid moisture exposure.

Follow these handling guidelines:

• Weigh out the required amount of peptide in a clean, dry environment to avoid contamination.
• Ensure the container is tightly sealed immediately after use.
• Store any remaining peptide at -20°C or below in an airtight container with a desiccant to absorb any moisture.

Storing peptides in these conditions will help prevent bacterial degradation, structural changes, and oxidation, extending their stability for years. However, peptides that contain amino acids such as cysteine, methionine, tryptophan, asparagine, glutamine, and N-terminal glutamic acid may have a shorter shelf life.

Dissolving Peptides

When dissolving peptides, use the recommended solvents based on your experimental setup. Sonication (using sound waves) can assist in dissolving peptides. Here are some general solvent guidelines:

• Sterile water is often the solvent of choice.
• Acidic peptides dissolve best in a basic buffer.
• Basic peptides dissolve better in an acidic buffer.
• Peptides with cysteine, methionine, or tryptophan require oxygen-free solvents to prevent oxidation.

Note: Peptides in solution are significantly less stable than in their freeze-dried form. Storing them in solution is generally not recommended, but if necessary, maintain them at -20°C using sterile buffers with a pH of 5-6 to extend their shelf life. To avoid degradation, it's best to have the peptide aliquoted (divided into smaller portions) ahead of time.
