What are the five results of humoral antigen-antibody binding? List and define each.
The antigen binding sites of an antibody molecule are located
The domain of an antibody molecule that is responsible for binding to the antigen is: a. Fab b. Fc c. the carbohydrate region d. antibody light chain e. Ig domain
The binding of an antigen to an antibody can result from all of the following except complement activation opsonization agglutination or precipitation activate T cells. neutralization of the antigen
Write T/F -specificty of an antibody binding is true to ONE antigen only -papain cleave of igG results in TWO fragments -discovery of J gene supports somatic recombination -affinity labeling reveals hypervaribale regions in light chains ONLY
B cells can attempt to increase the strength of antibody binding to antigen. In the answer box below, answer the following questions (in order). Where does this occur? What cells provide additional sources of antigen? What is this process called? Does this involve DNA rearrangement/recombination? What enzyme is required for this process(full name)?
1. Define antibody and antigen. 2. Explain why immunoassays are consider to be vary specific tests.

QUESTION 1 What is a heterophile antigen? a. an antigen homospecific to only one antibody. b. an antigen that has been modified to bind to more than one antibody. c. an antigen found only on one etiological agent. d. an antigen common to more than one species and whose distribution is unrelated to its phylogenetic distribution. 1 points QUESTION 2 What is an antigen? a protein synthesized and secreted by T lymphocytes (T cells). All bacterial cells are antigens....
Is more binding energy released when an enzyme encounters its substrate or when an antibody encounters it eliciting antigen? What is the implication here?
4. Review differences between antibody-mediated (hum between antibody-mediated (humoral immunity and cell-mediated immunity. 5. What is the cause, test and signs and symptoms of infectious mononucleosis? 6. How are lymphomas different from leukemias? 7. Describe the 2 major categories of lymphomas? 8. Leukemia • pathogenesis • signs and symptoms • acute vs. chronic • lymphocytic vs. myeloid leukemias • most common • treatment
