上海雅心生物技術有限公司成立于2008年，是我國*一家也是一一家專業進行重組胰蛋白酶和重組羧肽酶B研發和生產的企業。公司生產的重組羧肽酶B和重組胰蛋白酶已應用于重組胰島素生產中，并出口國外。重組羧肽酶B和重組胰蛋白酶從根本上解決了重組胰島素生產的動物源性問題。
   基于重組胰蛋白酶的細胞消化液為細胞培養生產抗體、疫苗等企業提供符合2010版藥典規定的胰蛋白酶，重組胰蛋白酶項目的研發和生產從根本上解決了動物源性胰蛋白酶的病毒、真菌、支原體等的污染問題。
   重組脂肪酶A是具有手性選擇性催化作用，可用于手性藥物的酶法催化生產和手性拆分。
   上海雅心生物技術有限公司堅持“科技創新”，相繼開發具有自主知識產權的產品，申請專利5項。2010年度，獲得科技部和上海市創新基金立項支持。
  Shanghai Yaxin Biotechnology Co. Ltd. was founded on 2008, is a high-tech enterprises, focuses on the research and producing the recombinant proteins. YaxinBio is the first and only a company on the research and producing the recombinant carboxypeptidase B and recombinant trypsin, both animal original  free enzymes specially used in the human recombinant insulin production to solve the animal-resource enzymes. 
   Recombinant trypsin is used in the cell culturing process, which conforms to the 2010 CP to the trypsin used in the cell culture. Animal original free is very important for the antibody and vaccine production. Usage of recombinant trysin fundamentally solve the problem of animal original virus contamination. Recombinant Lipase A with excellent enantioselectivity in biocatalytic hydrolysis.
YaxinBio insists on "scientific and technological innovation", has developed with independent intellectual property rights of the products. obtains Chinese ministry of science and technology and Shanghai innovation fund project support in 2010.
