Chinese name: American Peptide Technology Co., Ltd. mbth: Peptide Scientific Inc abbreviation: PSI Production Products: Polypeptide Synthesizer was established in 2002. Brief introduction, development history, products, brief introduction American Peptide Technology Co., Ltd. (PSI) is the world's leading manufacturer of polypeptide synthesizers. In the year when the company was founded, it successfully launched a large-scale automatic polypeptide synthesizer which meets the FDA standards and is suitable for GMP factories. The founding team of the company consists of the earliest biochemical experts in the United States. Every polypeptide synthesizer of PSI strives to achieve more reasonable design, more convenient operation, lower cost and more perfect synthesis from the user's point of view. At present, PSI has six series of polypeptide synthesizers, from scientific research to production and from single channel to multi-channel. Development history: 1995 A group of American biochemists who were the first to engage in polypeptide research and peptide synthesis designed and manufactured a fully automatic polypeptide synthesizer on the basis of summarizing previous experience, and took the lead in applying the principle of stirring without dead angle and recycling reagents to polypeptide synthesis, which not only greatly improved the solid-phase synthesis efficiency, but also reduced the use cost and made the operation more convenient and safe. After years of continuous improvement in use, PSI polypeptide synthesizer is almost perfect, and more and more medical practitioners hope to use PSI polypeptide synthesizer. In 2002, experts initiated the establishment of American Peptide Technology Co., Ltd. (PSI for short) in new york, USA, and devoted themselves to providing world-class polypeptide synthesizers for the vast number of experts and scholars engaged in polypeptide research and polypeptide production, hoping to promote the faster development of global polypeptide research and its industrialization. PSI polypeptide synthesizer is rated as the first choice by many R&D institutions for its more reasonable design and best synthesis efficiency. The company's customers include world-famous universities, research institutes and pharmaceutical companies, mainly including Columbia University, University of New Mexico, University of Michigan, Massachusetts Institute of Technology and other universities, as well as pharmaceutical companies such as Merck, Amgen and CBL in Europe. In 2005, Ye Ziqiang, one of the founders of the company, proposed to open the first branch in Asia, and in the same year, established the China office of PSI Polypeptide Technology Co., Ltd. in Shanghai. At present, China's customers mainly include Shanghai Academy of Life Sciences, Shanghai Zineng Pharmaceutical Co., Ltd., Beijing protein Research Institute, Beijing Zhongmu Co., Ltd., Shanghai Pharmaceutical Industry Research Institute, Chengdu Wuliangye Group and Tsinghua University. The polypeptide synthesizers produced by PSI Company are divided into: small-scale polypeptide synthesizers for laboratory use, pilot-scale polypeptide synthesizers, large-scale polypeptide synthesizers for GMP factories and multi-channel polypeptide synthesizers. At the same time, the polypeptide synthesizer can be customized for customers.
