How can the antigen antibody reaction help determine the degree of relatedness between species?
The antigen-antibody reaction can be used to determine the degree of relatedness between species by analyzing the specificity and affinity of antibodies produced against antigens from different organisms. When antibodies from one species bind to antigens from another species, the strength and pattern of this binding can indicate evolutionary relationships. Closely related species tend to show stronger binding due to similar antigens, while distantly related species will exhibit weaker or no binding. This immunological method complements genetic and morphological studies in assessing evolutionary connections.

Does an antigen cause an allergic reaction?
Only if the person is already allergic to that antigen. Not if they are immune to the antigen. The word antigen refers to the protein that joins with the antibody. If the antibody is of the allergic type (IgE) then an allergic reaction will happen and if the antibody is of the immune type (IgG, IgM or IgA) then there won't be an allergic reaction.
What is an Arthus reaction?
An Arthus reaction is a hypersensitivity reaction involving the in situ formation of antigen/antibody complexes after the intradermal injection of an antigen.
A reaction between an antibody and soluble antigen-forming lattices is called?
precipitation reaction
What is adjuvant?
Adjuvant is a subsatance that together with antigen increases antibody reaction.
What individual hypersensitivity to a substance usually antibody-antigen reaction is known as?
It is an allergy
Is pregnancy test an antigen-antibody 'agglutination' or 'preciptation' reaction?
Its an agglutination test
What bind with specific antigens in the antigen-antibody response?
The Fab portion of the antibody is what determines the idiotype. The Fab portion consists of both a heavy and light chain and is connected to the Fc region (isotype). Every B cell will express a different Fab structure and in a single B cell it will produce only the same Fab.
What is the effect of not including the antigen or the primary antibody in the ELISA reaction?
Not including the antigen will prevent the primary antibody from binding to it which will disrupt the results of the ELISA. Not including the primary antibody will prevent the secondary antibody from binding it, which will again negatively affect the results of the ELISA. All components are necessary to get an accurate ELISA.
What is the foreign material called that stimulates the production of an antibody?
do you mean antigens? An antigen is any (foreign) substance that stimulates an immune reaction.
What is the process by which an antibody binds to an antigen?
The process by which an antibody binds to an antigen is called antigen-antibody binding. This occurs when the antibody recognizes and attaches to a specific part of the antigen, forming a complex that helps the immune system identify and neutralize the antigen.
What is a nontreponemal antigen tests?
Nontreponemal antigen tests are used as screeners. They measure the presence of reagin, which is an antibody formed in reaction to syphilis.
Is glycoprotein an antigen or antibody?
Antibody
