Identifying The Individual Blood Types And Reactions Between Antigens And Antibodies

The purpose of this ABO-Rh Blood Typing Experiment is to identify the individual blood types and observe the reactions between antigens and antibodies. Blood is typed by the presence or absence of a specific antigen/s in the plasma membrane of a red blood cell. Depending upon the antigen/antibody reaction, we will be able to identify the unknown blood types in each of the samples.
Blood typing is extremely significant in the world we live in today. If you ever intend on donating blood or, in an extreme circumstance, need a blood transfusion, it is crucial to know what blood type you are. If one’s body is given mismatched blood, your antibodies will attack the antigens of the “foreign” blood. The attack will cause your blood to clump (agglutination), and can ultimately result in death. We are looking for any kind of clumping that occurs when the antigen (synthetic blood) antiserum (antibody) are mixed together.
Antigens are substances that can activate an immune response in the body. There are three main surface antigens: A, B, and Rh. Type A blood has surface antigen A only. Type B blood has surface antigen B only. Type AB blood has both surface antigens A and B. Type O blood has no surface antigens. Rh refers to whether the presence of antigen Rh is present or absent. If it is present, you use a plus sign (+). If it is absent, you use a negative sign (-).Thus, these create the blood types of A±, B±, AB±, and O±.
Each of these surface antigens are called…
