serum Serum refers to the light yellow transparent liquid separated from the fibrinogen after blood coagulation, or refers to the plasma from which fibrin has been removed. Its main role is to provide basic nutrients, provide hormones and various growth factors, provide binding proteins, provide contact-promoting and stretch factors to make cells adhere to the wall from mechanical damage, and to protect cells in culture. The main components of serum Serum is a very complex mixture formed by removing fibrinogen from plasma. Although most of its components are known, some of them are still unclear. The composition and content of serum often vary with the sex, age, and physiology of the blood supply animal. Conditions and nutritional conditions vary. Serum is a colloidal liquid without fibrinogen in plasma, which has the functions of maintaining the normal viscosity, pH and osmotic pressure of blood. It is mainly composed of water and various chemical components, including albumin, α1, α2, β, γ-globulin, triglycerides, total cholesterol, alanine aminotransferase and so on. Serum contains various plasma proteins, peptides, fats, carbohydrates, growth factors, hormones, inorganic substances, etc. These substances have a physiological balance to promote cell growth or inhibit growth activity.
