Fractional kill
Fractional Kill
Fractional kill (pronounced: /ˈfrækʃənəl kɪl/) is a term used in pharmacology and oncology to describe a phenomenon where a specific proportion of a population of cells is killed by a particular dose of a drug, rather than an absolute number.
Etymology
The term "fractional kill" is derived from the concept that a "fraction" or proportion of a cell population is killed by a drug dose. The word "fractional" comes from the Latin "fractio" meaning "a breaking," and "kill" comes from the Old English "cwellan" meaning "to kill, murder, execute."
