Multi- domain mAbs are far more complex than small molecule drugs with intrinsic heterogeneities. The critical quality attributes of a given mAb, including structure, post-trans- lational modifications, and functions at biomolecular and cellular levels, need to be defined and profiled in details during the developmental phases of a biologics. These critical quality attributes, outlined in this review, serve an important database for defining the drug properties during commercial production phase as well as post licensure life cycle managemenL Specially, the molecular characteriza- tion, functional assessment, and effector function analysis of mAbs, are reviewed with respect to the critical parame- ters and the methods used for obtaining them. The three groups of analytical methods are three essential and inte. gral facets making up the whole analytical package for a mAIPbased drug. Such a package is critically important for the licensure and the post-licensurs life cycle management of a therapeutic or prophylactic biologics. In addition, the basic principles on the evaluation of biosimilar mAbs were discussed briefly based on the recommendations by the World Health Organization.展开更多

It supplies microenvironment for Tcell differentiation and is directly involved in defense mechanism. The current status of the fish thymus research was reviewed in the following aspects: 1) structure and possible functions; 2) origin, histogenesis and degeneration; 3) ontogeny and function of Tlymphocyte obtained with monoclonal antibody.展开更多
