Ado Rh Blood Typing Experiment

Superior Essays
Introduction
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

On palate #3, we placed 1 drop of synthetic blood sample #3 in each of the wells labeled A, B, and Rh.
7. On palate #4, we placed 1 drop of synthetic blood sample #4 in each of the wells labeled A, B, and Rh.
8. We used three toothpicks per palate (blue, yellow, and red). We used the blue toothpick for well A. We used the yellow toothpick for well B. We used the red toothpick for well Rh.
9. Using the toothpicks, we stirred the synthetic blood and anti-serum in each of the wells for 30 seconds. Then we discarded toothpicks.
10. We examined the mixtures. We carefully looked for films or clumps left behind. If the sample had any of these characteristics, we knew agglutination had occurred. We also knew that a positive agglutination reaction indicates the blood type.
11. We recorded the results for each of the blood samples.
12. We cleaned the palates by drying up the mixtures in wells with a paper towel. Then we disinfected each palate with Simple Green and returned our supplies.

Blood type AB has both antigen A and B, but neither anti-A or B antibodies. The agglutination that occurred was a result of the presence of both antigens A and B reacting with the anti-A antibodies and anti-B antibodies. Antigens A and B recognized these anti-A antibodies and anti-B antibodies foreign to the cell, hence, an immune response took place. The positive was determined because there was a reaction in well Rh, proving that the Rh antigen was present. Type AB+ blood is considered to be a universal recipient because it lacks anti-A antibodies and anti-B antibodies. Therefore, they can safely receive any type of

    After that we pipetted 0.75 ml of buffer PE to the samples and spun it for another minute then disposed of the waste. The columns were added to the tubes and spun for a minute in the centrifuge to dry then planed in new clean tubes.

    The reticulocyte count determines how fast the red blood cells are made by bone marrow and released into the blood. The coagulation factor will also be tested more in-depth including factors VII and VIII assays. On the other hand, many drugs that are in the early phase of their discovery are tested using in-vitro hepatotoxicity testing. This is the recommended method to test the compound so one can see the molecular structure of the drug. It can be tested in a controlled environment with different variables added to make structured toxicology tests.…

The magnet was placed back into the cereal mixture and this same process was carried out 3 more times until there was no more iron present on the magnet. After the final extraction, pour the HNO3 solution into a 100 mL volumetric flask. Rinse the magnet three times with 10 mL of 1.0 M HNO3 and pour each rinse into the volumetric flask. After the three rinses, dilute the volumetric flask to the mark with 1.0 M HNO3.…

    Direct Coombs test is also called Direct Antiglobulin Test or DAT. This test is used for the detection of IgG or C3 antibodies which are attached to the RBC’s surface. These antibodies are important to be detected because they might sometimes cause anemia due to destruction of RBCs. DAT is mainly done on blood samples of newborns, especially when a newborn is suffering from jaundice. • Procedure: 1.…

Succeeding that, we put the lids of the petri dishes back on and cut around six inches of parafilm around all six of the petri dishes. We used parafilm in order to retain the water. Lastly, we placed all three of the trials under a florescent light until further data is collected. The seeds were under the light for a total of thirty-one hours.…

We recorded the number of borax solution drops for experiment C as double the borax solution for experiment B. We then added the same amount of glue and water in the beaker, and mixed it with a popsicle stick. We stretched this slime three times and recorded each measurement in our data table under experiment C. Finally, we found the average for this trial and recorded…

    PURPOSE The purpose of this lab is to acquire the ABO blood type of four unknown individual’s samples through a series of steps. Blood typing consists of a test in which ultimately determines an individual’s blood form. This procedure is an essential process for those who need blood transfusion or those willing to donate blood. The reason this stage is compulsory is because not all blood is compatible. Potentially a fatal transfusion reaction can occur if a unit of blood containing an ABO antigen to which the blood recipient has an antibody is transfused to the recipient.…
