What You Need to Know About Custom Peptide Synthesis


Custom peptides are used widely in the fields of research and development and formulation studies in addition to other commercial uses. The companies involved with the commercial manufacture of custom offer the products in both powder and solution forms.

Custom peptide synthesis is done to produce research grade peptides. Through synthesis, the peptides are modified to suit specific diagnostics or therapeutic usages. Basically, there are two types of custom peptide synthesis – solid and liquid synthesis. Liquid synthesis is applied for very short dipeptides while solid synthesis is the process used for large scale production.


Custom peptides are available in a wide variety and for various applications. Anyone in need of peptide is free to search and find the desired peptide based on their specific needs. Since there are still no restrictions limiting the use of peptides, you are free to order the peptides in any quantity, from as little as milligrams to massive kilos.

The following are some of the applications of custom peptides-:

  • Receptor characterization
  • Biological effect measurement
  • Epitome mapping
  • Protease assays
  • Protein-function structure analysis
  • Production of antibodies

It is imperative to handle and store custom peptide carefully for accurate results. Most of the custom peptides are delivered as trichloroacetic salts together with carbon molecules and free amino acids. Once received, it is recommended that the peptides be stored at -200C since the temperature can make the peptide stay stable for many years.

Other than the trichloroacetic salt peptides, you can also buy soliloquized peptides, but you will have to use them immediately because they are highly unstable.

When dealing with any peptide product, you should always have gloves on to avoid unnecessary contamination of the enzymes. Again, since most of the enzymes are sensitive to light, they should always be protected against direct sunlight.
