blood type o rh d negative diet

blood grouping experiment an adult human has about 4–6 litres of bloodcirculating in the body. blood consists of several types of cells including white bloodcorpuscles or wbc and red blood corpuscles or rbc floating around in fluid called plasma.there are certain protein molecules called antigens located on the surface of the redblood cells and antibodies which are in the

blood type o rh d negative diet, blood plasma. the differences in human bloodare due to the presence or absence of these antigens and antibodies. individuals havedifferent types and combinations of these molecules.according to the abo blood grouping system discovered by karl landsteiner, there arefour types of blood groups.

1. blood group a2. blood group b 3. blood group ab4. blood group o rh (rhesus) factor is found on the rbc's surfacein most people. like a and b, this is also an antigen and those who have this antigenare called rh+. those who lack this antigen on the surface of rbcs are called rh-.to conduct the experiment we require: • three monoclonal antibodies - anti-a,anti-b and monoclonal d kept in an icebox. • lancets• spirit • cotton balls• tooth pick • glass slide

procedure: 1. swab the finger with alcohol swab and takeblood sample using a lancet as shown. 2. take three separate drops of blood on aglass slide. 3. place a cotton ball on the finger to stopthe blood flow. 4. now, pour one drop each of anti-a, anti-band monoclonal-d on each drop of blood respectively. 5. mix the monoclonal antibodies with theblood sample properly using a tooth pick. (make sure you take a new tooth pick for mixingeach drop) 6. when rbcs carrying one or both antigensare exposed to the corresponding antibodies, they agglutinate; that is, they clump together.7. for e.g., in this slide, agglutination

occurred on the first and third drops whichcorresponds to antigen a and rh factor. so the blood group is a+.8. thus, we can identify the blood group by noticing the agglutination on the correspondingdrops.
