Neuritin, as one of the neurotrophic factors, plays an important role in the development of nerve and the repair of nerve injury. Recombinant human Neuritin is important to further study of its function and mechanism. It's know that the effective purification method is necessary to obtain the recombinant protein. The recombinant human Neuritin was obtained from AKTA purification system in previous study. In this study, we optimized the conditions of purification. The purity of recombinant human Neuritin is ...
