Hangzhou Longyang Biotechnology Co., Ltd. is located to the west of Wanshi, a town in the beautiful and wealthy Fuyang City. The company was founded in February 2008. Built on years of industrial experience, Longyang, with its main product crude heparin sodium as the starting material of pharmaceutical grade heparin, actively participates in the long heparin supply chain on the world scale. It focuses on the complete control of the raw materials supply and integration of upstream resources. The company is one of the first Chinese enterprises obtaining U.S. FDA approval and can directly export products to the U.S. market. Relying on advantages in upstream resources and technological innovation, Longyang is the first Chinese enterprise achieving 100% control of the entire supply chain to ensure its crude heparin sodium coming from healthy porcine intestines. Through collaboration with leading Chinese slaughtering companies such as Yurun, the company controls the product quality from the very beginning, porcine intestines. Currently, the company has a raw heparin workshop in Jiangsu, and the other two workshops are with total capacity of 100,000 procine intestines per day and the annual crude heparin capacity of 20 tons. Adhering to the sustainable development mode, the company will further expand its collaboration with leading Chinese slaughtering companies and plan to achieve the capacity of 200,000 procine intestines per day by 2015. Through years of heparin sodium producing and R&D Longyang has created a scientific, standardized and reliable technical system; through years of heparin sodium marketing and services Longyang has built a professional team. Longyang is the first Chinese crude heparin sodium producer taking the lead of abandoning the traditional raw material purchasing model, and produces 100% of its crude heparin sodium directly from healthy porcine intestine. Under the leadership of its core team, the company has built a new business model including the whole crude heparin sodium supply chain, from raw material collection and control, R&D, manufacturing, to final sales. It has also established a reliable manufacturing process, and a true SOP (Standard Operating Procedure) and documentation systems. The company has its own heparin sodium extraction and purification technology. Comparing to traditional production processes, the company's unique technology ensures consistent quality, high yield and high efficiency. The company's strength comes from strong technical know-how. The company has introduced advanced PCR and SAX HPLC testing technology and equipment, and is collaborating with leading technology institutions auch as Zhejiang University and several famous pharmaceutical companies to continuously enhance and optimize the existing heparin sodium extraction technology, production process and testing techniques, laying a solid foundation for the long-term development.
