👉 Antibody fluid, also known as the isotype fluid or plasma fraction, represents the liquid component of blood that carries antibodies. This fluid is primarily composed of various immunoglobulins (antibodies) of different classes, such as IgG, IgA, IgM, IgE, and IgD, each with unique functions and roles in the immune response. The fluid is responsible for transporting these antibodies throughout the body, enabling them to recognize and neutralize foreign substances like bacteria, viruses, and toxins. It also plays a crucial role in the immune system's ability to remember past infections and mount a faster, more effective response upon re-exposure. The fluid's composition and concentration can vary depending on factors such as the individual's immune status, health conditions, and exposure to pathogens.
