Abstract: Provided is a broad-spectrum, efficient and anti-tumor anti-TRAILR2 antibody-toxin-conjugate (ADC, named Zapadcine-1(a, b, c, d) and Zapadcine-3(a, b, c, d, e)). Toxin with cytotoxic effect is linked to an anti-TRAILR2 humanized monoclonal antibody by means of a covalent bond by using disulfide bond bridging or conventional coupling technology and chemical linkers, so as to form an anti-TRAILR2 humanized antibody-toxin-conjugate. The ADC has the specificity of TRAILR2 positive tumors, and after conjugated to TRAILR2, the positive tumors can be endocytosed into lysosomes of tumor cells, and is degraded by means of proteases inside the lysosomes to release free micromolecule urotoxins, so that different TRAILR2 positive tumor cells are killed specifically, the tumor growth is suppressed, the tumor cells are even completely eliminated, and the tumor is cured.

Each polymerization station can include a light source, such as an LED array, that irradiates material. Each light source can be in a lid of the prepolymerization station. When operation of one polymerization station is halted, such as for maintenance, then the system can increase the light source intensity of the remaining polymerization stations, slow the conveyor speed, or both.
