上海雅心生物技术有限公司成立于2008年，是我国**家也是一一家专业进行重组胰蛋白酶和重组羧肽酶B研发和生产的企业。公司生产的重组羧肽酶B和重组胰蛋白酶已应用于重组胰岛素生产中，并出口国外。重组羧肽酶B和重组胰蛋白酶从根本上解决了重组胰岛素生产的动物源性问题。
   基于重组胰蛋白酶的细胞消化液为细胞培养生产抗体、疫苗等企业提供符合2010版药典规定的胰蛋白酶，重组胰蛋白酶项目的研发和生产从根本上解决了动物源性胰蛋白酶的病毒、真菌、支原体等的污染问题。
   重组脂肪酶A是具有手性选择性催化作用，可用于手性药物的酶法催化生产和手性拆分。
   上海雅心生物技术有限公司坚持“科技创新”，相继开发具有自主知识产权的产品，申请专利5项。2010年度，获得科技部和上海市创新基金立项支持。
  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.
