Antiserum vs. Antibody: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on January 9, 2024
Antiserum is a blood serum containing antibodies against specific antigens, while an antibody is a protein produced by the immune system to neutralize pathogens.

Key Differences

Antiserum is a serum derived from the blood of an immunized individual or animal, containing a high concentration of antibodies. Antibodies, in contrast, are specific proteins produced by B-cells in the immune system, designed to recognize and bind to antigens, such as viruses or bacteria.

Antibody production is a key immune response, with each antibody being specific to a particular antigen. Antiserum, on the other hand, is a broader term encompassing a collection of antibodies, typically produced in response to exposure to a particular pathogen or toxin.

In medical treatments, antiserum can be used for passive immunity, as it provides immediate but temporary protection by introducing external antibodies. Antibodies themselves, whether naturally produced or introduced through antiserum, play a crucial role in identifying and neutralizing pathogens.

The creation of antiserum involves stimulating an immune response in a host and then harvesting the serum, which contains the antibodies. Each antibody within the antiserum has a unique structure that enables it to bind specifically to its corresponding antigen.

Antiserum is a practical application of immunology, offering a ready-made solution of antibodies, while antibodies are the fundamental components of the body’s adaptive immune response, each uniquely designed to combat specific antigens.

Antiserum

Human or animal serum containing antibodies that are specific for one or more antigens.
Sumera Saeed
Dec 19, 2023

Antibody

Any of numerous Y-shaped glycoproteins that bind to specific antigens and either neutralize them or cause them to be destroyed by other elements of the immune system, such as phagocytes, cytotoxic cells, or complement proteins. Antibodies occur as antigen receptors on the surface of B cells and are secreted as soluble proteins when the B cells mature into plasma cells. Antibodies are also called "immunoglobulins."

Antiserum

(medicine) A serum prepared from human or animal sources containing antibodies able to counter certain diseases or toxins.

Antibody

(immunology) A protein produced by B-lymphocytes that binds to a specific antigen.

Antiserum

Blood serum containing antibodies against specific antigens; provides immunity to a disease
Sumera Saeed

Antibody

Any of various bodies or substances in the blood which act in antagonism to harmful foreign bodies, as toxins or the bacteria producing the toxins. Normal blood serum apparently contains various antibodies, and the introduction of toxins or of foreign cells also stimulates production of their specific antibodies by the immune system.
Sumera Saeed

Antibody

More narrowly, any of the immunoglobulins present in the blood serum or other body fluids of an animal, which reacts with a specific antigenic substance, whether the antibody was produced as a consequence of the stimulus provided by the antigen, or was pre-existing prior to exposure of the organism to the antigen.

Antibody

Any of a large variety of proteins normally present in the body or produced in response to an antigen which it neutralizes, thus producing an immune response
