“Hey NEET PG aspirants! Bookmark this.

How do we name monoclonal antibodies?

-mab = monoclonal antibody

-mo-mab = mouse mab
-xi-mab = chimeric mab
-mu-mab = human mab
-zu-mab = humanized mab

Example: Ri-tu-xi-mab
-Tu = tumour directed (everything in oncology will have -tu)
-xi = chimeric
-mab = mab 🤷🏻

Rituximab is a tumour directed, chimeric, monoclonal antibody.”
