(1) An antibody is a protein which recognises a foreign molecule, known as an antigen.

(2) Secondly, this membrane sheet is treated with a solution containing an antibody to the protein of interest.

(3) An antibody is any protein that is released in the body in direct response to infection by an antigen.

(4) There were always free antibodies; there were antibodies in the blood for some weeks.

(5) A healthy body develops antibodies , which hopefully resist the antigens, by binding on them.

(6) In MS, the fluid may contain white blood cells, high levels of protein and certain antibodies .

(7) You have an immune response to the vaccine as your body develops antibodies to the virus.

(8) New therapies based on proteins and antibodies would stop in their tracks chronic diseases such as cancer.

(9) For example, if you are of blood type A, your body will generate antibodies to attack the B protein.

(10) We can reduce levels of that substance by introducing into the body antibodies that specifically recognize it.

(11) A surprising result [of the research] was that we could even make mice make antibodies to their own proteins.

(12) HIV infection is detected using a blood test that looks for antibodies created by the body as it tries to fight the virus.

(13) When exposed to an antigen, that is a virus or a bacterium, the body produces antibodies .

(14) Bcells are white blood cells which defend the body against viruses and bacteria by making antibodies .

(15) If you've already had it, your body has produced antibodies that fight the virus if you come into contact with it again.

(16) In its attempt to protect the body, it creates specific antibodies to the food.

(17) But if you have hay fever, your body produces antibodies in response to pollen.

(18) The levels of immune globulins and of certain antibodies in the blood may indicate a problem in the immune system.

(19) A blood test can detect antibodies to the hepatitis C virus and a positive test shows that you have been infected.

(20) Local government staff took blood samples from each truckload to test for virus antibodies .
