Research FAQ

All peptides sold by UK Peptides are strictly for research purposes only. They are not intended for:

Human consumption or use
Animal consumption or veterinary use
Therapeutic applications
Medical diagnosis or treatment

By purchasing from us, customers confirm they are acquiring these compounds for legitimate scientific research purposes only. We take this responsibility seriously and ensure all sales comply with UK regulations.

Peptides are short chains of amino acids linked together by peptide bonds. By precisely controlling the amino acid sequence, defined molecular structures can be created for targeted research applications. Peptides are widely used in biochemical signalling studies, receptor interaction research, and molecular pathway investigation.

How RP Peptides Synthesises Peptides

At RP Peptides, we manufacture research-grade peptides using Solid-Phase Peptide Synthesis (SPPS), a precise stepwise method that ensures accurate sequence assembly. The process begins by anchoring the first amino acid to a solid resin support. Protected amino acids are then added sequentially to build the desired chain in a controlled manner. Once synthesis is complete, the peptide is cleaved from the resin, protective groups are removed, and the product is purified to ensure high sequence integrity. The final material is lyophilised to produce a stable, research-ready powder.

All products supplied by RP Peptides are intended strictly for laboratory research purposes and are not for human consumption.

Proper handling and storage are essential to maintaining peptide integrity and performance in research applications.

Before opening a vial, allow it to reach room temperature for approximately 15–20 minutes. This prevents condensation from forming on the cold lyophilised powder, which can introduce unwanted moisture. Where possible, warming the vial in a desiccator or dry box provides additional protection against humidity.

During handling, always work in a clean laboratory environment and use clean, dry equipment. Only remove the quantity required for immediate use and reseal the container promptly to minimise exposure to air and moisture.

For storage of unreconstituted peptide, material should be kept at –20°C or lower in a tightly sealed container with desiccant. Protection from light and humidity is strongly recommended. For long-term storage, aliquoting into smaller portions can help avoid repeated freeze–thaw cycles, which may compromise stability.

For reconstitution, sterile water or bacteriostatic water is commonly used. However, solvent choice should consider peptide characteristics. Acidic peptides may dissolve more effectively in slightly basic buffers, while basic peptides may require mildly acidic conditions. Peptides containing oxidation-prone residues such as cysteine (Cys), methionine (Met), or tryptophan (Trp) should ideally be prepared using oxygen-reduced solvents. Gentle swirling or brief sonication can assist dissolution without causing degradation.

Once reconstituted, solutions should be refrigerated immediately at 2–8°C. Sterile buffers within a pH range of 5–6 may help extend stability. Wherever possible, only reconstitute the quantity required for immediate experimental use. If storage of solution is necessary, keep at –20°C and avoid repeated freeze–thaw cycles to preserve peptide integrity.
