Describe how an agglutination reaction is different
from a precipitin reaction on terms of what is occuring between the
antigens and antibodies
Homework Answers
Agglutination:
Insoluble Antigen binds with soluble Antibody to form a visible clumps. One such good example for agglutination is hemagglutination, where RBC agglutinate with Antibody to form clumps.
Precipitation:
When soluble Antigen binds with soluble Antibody it forms an insoluble solid mass through a chemical reaction known as precipitation. Among the immunoglobulin, IgG Antibody has the strongest capability for precipitation.

A microsope slide showing agglutination when blood is mixed with antisera. our red blood cells are much stronger antigens and large aggregated clumps will be readily visible when agglutination has occurred. If you have neither A nor B antigen on your red blood cells, you will have no agglutination of either antisera and therefore the cells are blood type 0. Figure 4 shows a picture of aggluti-nation when cells clump or aggregate. No agglutina-tion is a smooth suspension of cells...

Background INFO
There are four types of blood: A, B, AB, and O (Figure 4). Each
is characterized by the glycoproteins (proteins with a sugar
attached) and lipoproteins (proteins with a lipid attached)
embedded in the surface of red blood cells (RBCs). In addition to
type, blood can be rhesus (Rh) factor positive or negative.
These proteins are inherited and may differ from individual to
individual. If, during a transfusion, an individual receives
blood with the incorrect RBC proteins (for...

1. Define the terms: antigen, hapten, epitope, paratope (slide 43), agretope (slide 40), and immunogen. Describe the differences in how B and T cells and their antigen receptors see antigens and what those differences mean as far as composition of antigens that can be recognized by B and by T cells.

1. Select the statements that correctly describe the role of the thymus, spleen, and lymph nodes in adaptive immunity. Select the TWO answers that are correct. The thymus is the site of T cell development. The thymus and lymph nodes work together in humoral immunity. The thymus and spleen produce B cells. Lymph nodes and the spleen filter pathogens from lymph and blood. The lymph nodes secrete lymphatic fluid. 2. How do humoral immunity and cell-mediated immunity differ? Select the...
