XL Peptides Support

Making a peptide one amino acid at a time sounds straightforward. But the difficulty is keeping the growing chain under control while repeatedly adding new amino acids and removing unwanted reaction materials. Solid-phase peptide synthesis (SPPS) solves much of this problem by keeping the growing peptide attached to a solid material called a resin. Instead … Read more

When looking at a peptide specification sheet or Certificate of Analysis (COA), you may see a short string of letters such as AGSLK. At first glance, it can look like a code with little practical meaning. That code is the peptide sequence. It shows which amino acids make up the peptide and, importantly, the exact … Read more

Peptides are sensitive research compounds. Their stability can be affected by temperature, moisture, light, oxygen exposure, pH, and the peptide’s chemical structure.  Because of this, storage conditions are an important part of maintaining sample integrity in non-human laboratory research. In many research settings, dry lyophilised peptides are stored cold for longer-term stability. However, refrigeration is … Read more
