Solutions for Peptide Synthesis, Cell Culture Media, and More

Baishixing specializes in developing and manufacturing high-value amino acid-based products. All of our offerings originate from core amino acid technologies, which we further optimize into two major categories of specialty amino acids:

  • Specialty amino acids for cell culture media
  • Specialty amino acids for peptide synthesis

These customized amino acids also serve as building blocks for the production of related raw materials and pharmaceutical intermediates. Our R&D efforts focus on enhancing functionality and performance across applications in biopharmaceuticals, nutrition, and other health-related industries.
