👉 Bernard fluid, also known as Bernard's fluid or Bernard-Guérin fluid, is a colloidal suspension of proteins derived from the kidneys of certain fish species, particularly the European eel (Anguilla anguilla). This fluid is notable for its unique properties, including the ability to maintain its viscosity and structure in a wide range of temperatures and pH levels, making it an ideal model for studying protein behavior under various conditions. Bernard fluid is primarily composed of immunoglobulins (antibodies) and other proteins, which remain stable and active even when exposed to extreme environments, such as high salinity or temperature fluctuations. This stability has made it a valuable tool in biochemistry and molecular biology research, especially in understanding protein folding, interactions, and the mechanisms of protein stability.
