You immunize a mouse with Salmonella O antigen. You collect the serum from this mouse and mix it with Salmonella H antigen. Would you observe agglutination? Why or Why not?
Homework Answers
Yes, you will observe agglutination. Remember that when we immunize an organism, we induce the production of antibodies against a specific antigen. One of the main mechanisms of action of antibodies is the agglutination. If we mix the serum (which contains the antibodies against the antigen) with the Salmonella antigen, the antibodies in the serum will recognize the antigen and it will be observed an agglutination process

You inject a mouse with a protein antigen X. This is the first time the mouse has been exposed to X. In the course of clearing X from their body the mouse will launch an immune response to antigen X. Over the course of the immune response antigen X will encounter naïve, effector and memory lymphocytes (B- and T-cells). There are distinct differences between the function and role of each type (naïve, effector and memory). Differentiate between naïve, effector and memory...

QUESTION 1 What is a heterophile antigen? a. an antigen homospecific to only one antibody. b. an antigen that has been modified to bind to more than one antibody. c. an antigen found only on one etiological agent. d. an antigen common to more than one species and whose distribution is unrelated to its phylogenetic distribution. 1 points QUESTION 2 What is an antigen? a protein synthesized and secreted by T lymphocytes (T cells).

Human blood types A, B and O are associated with the carbohydrate antigens A, B and H respectively. A and B antigens are caused by an alteration of H antigen. Normally everyone can synthesize H antigen (a cell surface carbohydrate found on red blood cells and other cell types). Some people make A and/or B transferase(s) which converts the H antigen to an A and/or B antigen respectively. The H antigen is produced by a specific fucosyltransferase encoded by the...

When performing immunocytochemistry experiments, what is the purpose of the blocking serum? If you only had access to normal mouse serum, from what species would your primary and secondary antibodies need to be derived? Is it possible to fluorescently label two different proteins in the same cell using the same immunocytochemistry techniques? If so, what considerations would you need to make for your primary and secondary antibodies? Is it correct that the primary and secondary antibodies have to be from...

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...

Two proposed computer mouse designs were compared by recording wrist extension in degrees for 24 people who each used both mouse designs.t The difference in wrist extension was calculated by subtracting extension for mouse type B from the wrist extension for mouse type A for each person. The mean difference was reported to be 8.82 degrees. Assume that this sample of 24 people is representative of the population of computer users. (a) Suppose that the standard deviation of the differences...
