Beijing Dylan Biotechnology Co., Ltd, focusing on the development of peptide synthesis, cleavage, cyclisation and other related equipment, independently developed the stirred production peptide synthesiser, cleavage instrument, and provide peptide synthesis total solutions for pharmaceutical companies, peptide CRO/CDMO/CRDMO companies, research institutes, etc. Peptide Scientific Inc (PSI) is the creator of 180-degree mechanical stirring mode, which has the highest synthesis efficiency. PSI has single/multi-channel R&D, pilot, single-arm support mini production, and double-arm support production series of fully automated peptide synthesizers. Advanced ChemTech (ACT) is the authorised peptide synthesizer maintenance service provider, and the Tetras 106-channel fully-automated asynchronous peptide synthesizer has been successfully developed by ACT for the construction of custom peptides, antigenic peptides, catalogue peptides, peptide libraries, and micro-peptide libraries. Tetras is the mainstream device used by peptide customisation service companies worldwide.
