Peptides play a crucial role in fundamental physiological and biochemical functions of life. For decades now, peptide research is a continuously growing field of science. Peptide is a molecule formed by joining two or more amino acids. When the number of amino acids is less than about 50 these molecules are named peptides while larger sequences are referred to as proteins. The amino acids are coupled by a peptide bond, a special linkage in which the nitrogen atom of one amino acid binds to the carboxyl carbon atom of another. Peptides (proteins) are present in every living cell and possess a variety of biochemical activities. They appear as enzymes, hormones, antibiotics, receptors, etc. Synthetic peptides may be useful in structure-function studies of polypeptides, as peptide hormones and hormone analogues, in the preparation of cross-reacting antibodies, and in the design of novel enzymes.

We do not provide in assistance in choosing your peptides. Please read some research articles online to help you choose.

We can help our customers understand how to store, mix, and calculate mcg/ml in their solution. Every other question you may have we cannot help with. We always recommend researching online to learn more about each peptide by searching the product name.

Peptide storage is important to ensure their quality is maintained at the highest level possible. We always suggest storing peptides in a fridge or freezer, but they are stable at room temperature for up to a month depending on sequence length etc. Below are our suggested storage guidelines: Mixed Peptides Storage Reconstituted (mixed) vials must be stored in the refrigerator (2 to 8 degrees Celsius) Expiry Use within 3-8 weeks of mixing. (Sequence dependent) Unmixed Peptides Storage: In powder (lyophilized) form vials can be stored frozen (0 to -20 degrees Celsius). Expiry Will remain stable up to 48 months (4 years) in the freezer. We recommend using within 18 months of purchase. Unmixed vials can be stored in the freezer for a period of up to 48 months (4 years); however, if you are going to use the vials within 1-3 months then you can store them in the refrigerator as repeated freeze-thaw cycles can cause damage to the peptide.

We always suggest following a strict mixing procedure. Prior to adding any mixing solution make sure both peptide and solution are at room temperature. This will make sure your peptides are effectively mixed every time. Then gently add your mixing solution into the vial, making sure to drip the solution down the side of the vial to protect the peptide. Then give the vial a gentle swirl before storage for 24 hours in a refrigerator. At that point, the peptide is ready to use.
