The Global Immunotoxins Market Size is Anticipated to Exceed USD 309.70 Million by 2033, Growing at a CAGR of 8.19% from 2023 to 2033. An artificial protein with a toxin attached to its targeting section is called an immunotoxin. The toxin kills the cell when the protein attaches itself to it and is ingested by endocytosis. An antibody is chemically coupled to a complete protein toxin, stripped of its native binding domain, to produce immunotoxins.
