BOC Sciences provides technical articles related to amino acids, peptides, and peptide nucleic acids (PNA).
Amino acids，a class of organic compounds that contain amino and carboxyl groups are one of the many biologically active macromolecules that build biological organisms, and are the basic materials for building cells and repairing tissues. With a variety of special functional groups and diverse structures, amino acids have a wide range of applications in pharmaceutical, food, cosmetic and other fields.
Amino acid analysis techniques include paper chromatography and thin layer chromatography, gas chromatography, high performance liquid chromatography, capillary electrophoresis, high performance anion exchange chromatography-integrated pulsed amperometric detection (HPAEC-IPA), etc.ric detection (HPAEC-IPA), etc.

According to their molecular structure, peptide synthetic reagents can be roughly divided into carbodiimides, phosphonium salts, uronium salts, organophosphorus, and other types of coupling reagents. Among them, carbodiimides, uronium salts, and phosphonium salts are the major three categories. Carbodiimides are first developed and most commonly used while uronium salts and phosphonium salts perform best with wide applications.

Cell-targeting peptides are short peptides that specifically bind to receptors on the surface of specific types of cells and facilitate the targeted delivery of drug molecules, or other therapeutic molecules to these cells. These peptides are able to selectively recognize specific cells, thereby increasing the targeting of therapeutic molecules and the efficacy of drugs while reducing adverse effects on healthy cells.
