Though research group’s joint effort of Beijing Yinfeng Dingcheng Biological Engineering Technology Co., Ltd, the patent “the segregation apparatus of adscs” which was applied in May 9, 2016 passed the approval of State Intellectual Property Office officially in November 16, 2016 and this company acquired the Utility Model Patent Certificate of this invention.

This segregation apparatus of adscs has some features with popularization convenience and simple and reasonable structure. This apparatus is equipped with stirring paddle which can stir tissue fluid of split cavity efficiently and solve heterogeneity of filter membrane because of the weight variation of tissue fluid. This may lead to some problems that the binding rate between separated adscs and specific captured antibody film is lower and the utilization ratio of filter membrane is also lower. In addition, stirring paddle is designed as heliciform which can raise the efficiency of stirring and decrease the damage to cells.

At present, Beijing Yinfeng Dingcheng Biological Engineering Technology Co., Ltd. has patents in the research of more than 10 items, two of which are being checked in utility model patent’s State Intellectual Property Office, seven of which have finished Technical clarification document and two pf which are preparing to declare. Beijing Yinfeng will continue to promote scientific and technological innovation, implement innovation-driven development strategy, promote the intellectual property’s innovation work and achieve the common development of scientific research and innovation.
