Therapeutic antibodies and barriers
WebbThere are many barriers to therapeutic mAb devel- opment, besides achieving the desired affinity to the antigen. These include intrinsic immunogenicity, chemical and confor- mational instability, self-association, high viscosity, polyspeci- ficity, and poor expression.
