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?

Answer #1

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

    1)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 lymphocytes.  Focus...

    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...

  • How do you get a knockout mouse ?

    So you knocked out a gene in embryonic stem cells you have taken from one white mouse. And then you put those cells into another blactocyst from a black mouse. Thus, you get a mix blactocyst. You put the blastocyst into a pseudo-pregnant mouse. The female gives birth to chimeric and normal mice. Then you take one chimeric mouse and mate it with a white wild type black. As a result you get mice of plain colour and not chimeras....

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...
