immunoglobulins
They are Proteins =)
Type A blood will produce antibodies against B antigens.
gamma globulins
Antibodies belong to the class of macromolecules known as proteins. They are Y-shaped proteins produced by the immune system in response to the presence of foreign substances called antigens.
According to the AB0 blood group system there are four different kinds of blood groups: A, B, AB or 0 (null). Blood group A If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma. Blood group B If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. Blood group AB If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma. Blood group 0 If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.
The term "hapten" does not belong in the list because it is not a complete antigen. Haptens are small molecules that can bind to antibodies, but they are unable to induce an immune response on their own.
Blood types are extremely important in blood donation! Depending on the blood type, the red blood cells have a unique antigen (a special protien) that identifies that type of blood. Antibodies will react to foreign blood types based on the antigen they exhibit. Mixing blood from two individuals can lead to blood clumping or agglutination. The clumped red cells can crack and cause toxic reactions. This can have fatal consequences. If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma. If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma. If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.

T-cells are one of two white blood cells (lymphocytes) that are necessary to fight off an invader (virus, bacteria) that doesn't belong in the body. There are different types of T-cells: Helper T-cells, T-cytotoxic cells and T-suppressor cells. T-cells do not make antibodies. The other white cell necessary to fight of that invader are B cells which make antibodies. Both cells are needed for us to fight off the various invaders. It is a very complex but smoothly run "war room".

The red blood cells define the blood group you actually belong to. There are small markers known as antigens on the red cells surface, but they are so tiny that it cannot be viewed under a microscope. However, every person has different antigens but for identical twins. The antigens identify the blood types and are the key to match the transfusions as well that helps in avoiding serious complications. The blood group structure is defined as the ABO system. Another significant factor worth considering is the Rh system. All the blood groups have the possibility of having Rh antigens. Conversely, there are some who have it, while some do not have it. In case, the blood group belongs to Rh antigens, then they are Rh positive and a person having A blood group with Rh positive is recognized as A+. In case a person has A blood group with Rh negative, then it is A-. This is the same pattern followed for O, B or AB blood group as well. The Rh system duals the blood groups effectively so that the positive blood type does not get mixed with negative.
