1. Explain why antibodies allow scientists to target and identify specific disease agents. The primary antibodies attach to the antigens that have the same receptors and the secondary antibodies do the same with the primary antibodies. 2. Why is the secondary antibody used in an ELISA test conjugated with an enzyme? What happens when this enzyme meets up with its substrate? The enzyme represents the weapon that the secondary antibodies (police) utilize to kill the antigen (foreign object)

Why is this technique a direct method? It is considered a direct method because it involves conjugation of an antibody with fluorescent dye. 5. What is an elementary body?

cases‚ the host survives and regains its health. This is because of the presence of antibody and lymphocyte in the blood of an individual that neutralize and attack foreign objects that can cause certain diseases like cancer. In order for us to produce large amounts of antibodies and lymphocytes to suppress foreign objects; we must have an enhanced immune system. The researcher investigated on how to increase the antibody and lymphocyte count to have protection against infectious diseases. Agaricus

RHOgam! RHOgam refers to Rho immunoglobulin. RHOgam is an injectable blood product used to protect an Rh-positive fetus from antibodies produced by its Rh-negative mother. The injections are given at about 28 weeks in the pregnancy and immediately after delivery. With these injections‚ Rh-negative women can have safe Rh-positive pregnancies. Rh is short for Rhesus factor. Rhesus factor is a type of antigen present on the surface of red blood cells. If you have this particular antigen‚ you

It is a system of classifying blood based on the presence of protein on the surface of the plasma membrane on the RBC. The protein is called antigen which is accompanied by antibody. B. Why is it important for everyone to know their own blood type? Because every antibody will react to a different RBC with different antigen causing

"When we’re laughing‚ natural killer cells that destroy cancer cells increase‚ as does the level of Gamma-interferon - a disease-fighting protein‚ T-cells - a major part of the immune system‚ and B-cells - which make disease-destroying antibodies. Laughter may also increase the concentration of salivary immunoglobulin A‚ which defends against infectious organisms entering through the respiratory tract so it helps us to resist colds and viruses." That makes quite a case of the adage "A barrel
