Bispecific Antibody Production Service Features

A bispecific antibody is an artificial antibody containing two kinds of specific antigen binding sites and can establish a bridge between target cells and functional molecules (cells) to stimulate a directed immune response. It is a genetically engineered antibody, which has become a hot spot in the field of antibody engineering, and has a broad application prospect in tumor immunotherapy. Based on the optimized mature mammalian cell expression platform, Sino Biological can provide you with fast and efficient bispecific antibody expression service.
