Summary Introduction
Introduction:
The blood is analyzed for the existence of a specific antibody and antigens by a method termed as serology. There are wide range of serological tests available to recognize the antigens or antibodies in the blood. Using tagged or labelled antibody to identify an antigen is an altered form of serological testing method, for example ELISA, fluorescent antibody tests (direct and indirect), and immunoblotting tests. ELISA uses enzyme labelled anti-antibody as a reagent that attaches to the antibody (binds to antigen of choice).

Which DOES NOT describe monoclonal antibodies?
Group of answer choices
a. Monoclonal antibodies are produced in test tubes by hybridoma cells
b. Monoclonal antibodies are specific to multiple antigens
c. These antibodies are used in diagnostic tests
d. The antibody producing cells may come from a non-human source
An epitope associates with which part of an antigen receptoror antibody?(A) the tail(B) the heavy-chain constant regions only(C) variable regions of a heavy chain and light chaincombined(D) the light-chain constant regions only
Labs that do a lot of Western blots often have hundreds of primary bodies but only two or three secondary antibodies. Why?
I understand that secondary antibody aids in the detection, sorting or purification of target antigens by binding to the primary antibody which directly binds to the target antigen. However, I don't undrstand why there are only two or three secondary antibodies available in the laboratory. Glad if the expert would advise.

- A researcher discovers that a breed of rabbits have antibodies that can neutralize HIV. The researcher decides to extract the antibody concentrated plasma and deliver it to a patient with HIV. What would you likely expect to see? a. The HIV patient will now have a fighting chance to eliminate HIV as the antibodies will not discriminate and bind to the same viral antigenic determinants. b. The HIV patient will form antibodies against the rabbit serum antibodies. c. The rabbit antibodies will opsonize the HIV antigenic determinants on the MHC II. d.
