These glycoproteins circulate in the blood and bind to specific foreign antigens, triggering an immune response. They are produced by plasma cells.

A type of immune cell that produces antibodies. They are generated from activated B cells.

A type of B cell that persists in the body after an infection. They can quickly respond to the same antigen upon re-exposure.

The process of identifying and activating a specific lymphocyte that binds to a particular antigen.

The ability of an antigen to trigger a strong immune response.

The process that occurs when an antigen binds to its specific receptor on a lymphocyte, leading to its activation and proliferation.

A substance that triggers an immune response. It is typically foreign to the body.

The ability of an antigen to bind to a specific antibody or receptor.

A type of antibody found in the blood, typically involved in rapid destruction of incompatible red blood cells during transfusion.

The process of red blood cell lysis (destruction) occurring within the blood vessels, often triggered by IgM antibodies activating the complement system.

A specific type of immunoglobulin with a structure consisting of two 'heavy' chains and two 'light' chains, responsible for 70-75% of total immunoglobulin concentration.

The ability of a molecule to bind to two antigens simultaneously, like IgG antibodies.

A method used to detect antigen-antibody complexes, especially those involving IgG antibodies, which are too small to cause visible agglutination (clumping) in saline.

Specialized receptors on placental cells that allow the transfer of IgG antibodies from the mother to the fetus during pregnancy.

A condition that occurs when maternal IgG antibodies attack fetal red blood cells, leading to their destruction.

The ability of a molecule to bind to two antigens simultaneously, like IgG antibodies.

The strength of the bond between an antigen and its corresponding antibody.

The first exposure to a specific antigen.

The immune response to a second or subsequent exposure to the same antigen.

The antibody isotype that is typically the dominant antibody produced in the secondary immune response.

The antibody isotype that is typically the dominant antibody produced in the primary immune response.

The process by which B cells switch from producing one isotype of antibody to another.

The process by which B cells produce antibodies with increasingly higher affinity for a specific antigen.

An immune complex forms when one or more antibodies bind to an antigen.

The affinity describes the strength of the bond between a single antibody binding site and its corresponding antigen epitope.

Avidity describes the overall strength of the interaction between multiple antibodies and their corresponding antigens; it's influenced by the affinity of each individual binding, the number of binding sites, and the arrangement of the epitopes.

Association constant (Ka) represents the rate of forward reaction (antibody binding to antigen), while dissociation constant (Kd) reflects the rate of the reverse reaction (antibody detaching from antigen).

The relative rates of the forward and reverse reactions determine the equilibrium of the binding process. A higher Ka means a faster forward reaction rate, favoring immune complex formation.

The goodness of fit between an antibody and its antigen is crucial, like a lock and key. Factors like size, shape, and charge of the antigen influence the binding.

Non-covalent forces like electrostatic forces, hydrogen bonding, hydrophobic bonding, and van der Waals forces contribute to the stability of immune complexes.

The combined effect of these non-covalent forces determines the overall strength and stability of the interaction between antigen and antibody molecules.

Electrostatic forces, hydrogen bonding, hydrophobic bonding, and van der Waals forces are the four key types of non-covalent interactions that contribute to the binding of an antigen to an antibody. These forces are weak individually but collectively contribute to strong and specific interactions.

Electrostatic forces, also known as ionic bonding, occur between oppositely charged regions of molecules. A positive charge attracts a negative charge. The strength of these interactions is influenced by the distance between the charges and the dielectric constant of the medium.

Hydrogen bonding occurs when a hydrogen atom is shared between two electronegative atoms (like oxygen or nitrogen). This type of interaction is relatively weak but occurs in many biological systems, including antigen-antibody binding.

Hydrophobic bonding arises from the tendency of water molecules to exclude non-polar molecules. This exclusion creates a force that drives non-polar molecules together, leading to interactions between hydrophobic regions of the antigen and antibody.

Van der Waals forces are weak, short-range attractions that arise from temporary fluctuations in electron distribution around atoms. These forces are only effective at very close distances and are important in antigen-antibody interactions.

Red cell antigens are components of the red blood cell membrane or protrusions from it. These antigens are responsible for triggering immune responses, which can lead to the production of antibodies against these specific red cell antigens.

Red cell antibodies are proteins found in the plasma or serum that can bind to specific red cell antigens. These antibodies are responsible for identifying and destroying red blood cells that possess the corresponding antigen. This process is essential for immune defense, but it can also cause complications if the wrong blood type is transfused.

Antigens are molecules that can bind to specific antibodies or receptors. They are typically foreign to the body and trigger an immune response. Understanding antigens is crucial in blood banking and transfusions, as they determine blood type and potential incompatibilities.
