Introduction to the Western Blot Technique The Western Blot, also scientifically known as the protein immunoblot, stands as a fundamental and highly versatile analytical technique in molecular biology and biochemistry. Developed in 1979 by Towbin and colleagues, this method allows researchers to identify specific proteins within a complex mixture, typically extracted from cells or tissues, […]
Definition and Fundamental Role in Immunity The term antigen (n.) refers to any substance that the immune system recognizes as being foreign, non-self, and potentially dangerous, thereby triggering a robust immune response aimed at neutralizing or eliminating the perceived threat.
