Abstract
Monoclonal antibodies (mAbs) are magic bullets proved to be a wonder in the pharmaceutical as well as medical fields. These are produced by various methods like hybridoma technology, phage display technology, YAC technology, and transgenic animals and plants. Based on the percentage of animal origin, mAbs are divided into chimeric, murine, humanized, and fully human. This review covers the history and methods of mAb production, immunotoxicity (Immunosuppression, immunostimulant, autoimmunity, hypersensitivity) associated with mAbs, and targets of mAbs. It also compiles mAb production using AI, new modifications, and novel mAbs, with its various clinical trial information ensuring the use of mAbs in rare diseases and disorders.
