Latest research
Peptide Academy
Peptide, protein, and hormone are answers to two different questions — how many amino acids a chain carries, and what role the molecule plays in the body's signaling. An overview of the boundaries, three-dimensional structure, the overlapping set of peptide hormones, and how correct classification translates into buying laboratory samples.
Peptide Academy
Melanotan II returns to the spotlight of research attention every summer. See the molecule through laboratory eyes: receptor biology, measurable melanogenesis, sample stability in heat, and the checkpoints of a trustworthy certificate of analysis.
Peptide Academy
The peptide bond is the amide linkage that condenses amino acids into the backbone of every peptide. Understand its chemistry from resonance to hydrolysis, and learn how to protect sample stability in the laboratory.
