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 scenario best describes antibody cross-reactivity? A. A single pathogen with multiple epitopes is recognized by a multivalent antibody. B. Multipleepitopes are recognized by multiple antibodies C. A single epitope is recognized by multiple antibodies D. Two distinct, but structurally similar epitopes are recognized by the same antibody   3. What is the major benefit of cross-reactivity? A. Cross-reactivity permits the allergic response. B. Cross-reactivity promotes a faster immune response against unrelated pathogens. C. Cross-reactivity enhances immunity by providing protection against related pathogens. D. Cross-reactivity allows the immune system to respond to pathogens in various locations within the host (i.e., skin, mucosal tissues, extracellular fluids, etc.)
