Definition of the word serum

The word "serum" has a fascinating origin! It comes from the Latin word "sērum," which means " juice" or "liquid." In medical contexts, the term referred to the clear liquid part of blood or plasma, separating from the blood cells through centrifugation. This liquid, rich in proteins and antibodies, was seen as a valuable component for treating various diseases. In the late 19th century, scientists like Emil von Behring and Shibasaburo Kitasato isolated antibodies from this liquid to develop the first vaccines. They recognized the power of serum therapy in combating diseases like diphtheria and tetanus. The term "serum" eventually became synonymous with any liquid preparation containing antibodies or other therapeutic agents, used to prevent or treat diseases. Today, the word "serum" is widely used in medicine, biotechnology, and even popular culture – from beauty products to gaming terminology! Its origins showcase the groundbreaking work of scientists who unlocked the secrets of the human immune system.
