Immunotoxins are proteins that include a toxin along with an antibody or growth factor that binds specifically to target. An immunotoxin consists of a specific cell-targeting constituent, usually a monoclonal antibody (mAb) linked to a cell-killing toxin. Chemical conjugation of antibody to whole protein toxin creates immunotoxins, lacking of its natural binding domain. Immunotoxins are created in Escherichia coli that are distorted with a plasmid encoding the recombinant toxin. Harvesting recombinant protein is the most common method for manufacturing a substance for clinical trial. The insoluble protein is washed thoroughly with detergent to remove solublized, endotoxin, denatured, and condensed in guanidine-dithioerythritol solution. Then the recombinant protein is restored as a denatured protein or also known as renatured protein by rapid intensity into redox buffer containing glutathione and arginine, and the dialyzed renatured protein purified by sizing chromatography and anion exchange.

Toxins used in immunotoxin structures are derived from fungi, bacteria and plants, while most function by inhibiting protein synthesis. The bacterial toxins that are commonly used in immunotoxins include the toxin from Pseudomonas exotoxin (PE) and Diphtheria toxin (DT). Ribosomes inactivating proteins (RIPs) gelonin, the A chain of ricin (RTA), pokeweed antiviral protein and dodecandron are included in plant toxins that are utilized in immunotoxins. As it is an enzyme, one toxin molecule can work on many substrate molecules, having a lethal effect on the cell. Immunotoxin’s use in haematological malignancies is considered to be very important, which are characterized by a high percentage of malignant cells that express the target antigen in contrast to solid tumours, which are characterized by a mixed cell population, and cells that are often not...
