1. Define antibody and antigen.
2. Explain why immunoassays are consider to be vary specific tests.
1)Answer- Define antibody and antigen
Antibody= It is defined as the protective chemicals produced by immune cells in response to antigens are called as antibody .
OR
It is also defined as an antibody is a Protein produced by immune system that is capable of binding with high specificity to an antigen it is called as the antibody .
Antigen= It is defined as the any foreign substance invading body and capable of stimulating an immune response, is called an antigen .
1. Define antibody and antigen. 2. Explain why immunoassays are consider to be vary specific tests.
portion of the antibody that makes it specific for the antigen is 14) Which number on the diagram is labeling the binds to? A) 1 B) 2 C) 3 D) 4 E) 5
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....
ELISA 1. This ELISA method coats a 96 well plate with the antigen opium. If the patient's serum contains antibodies for opium, their primary antibody will bind to the antigen. Then a secondary conjugated antibody is used to bind to the primary antibody. What specific testing method, utilizes two types of antibodies? 2. Which ELISA method coats a 96 well plate with the antibodies that target THC? If the patient's serum contains the antigen THC, then they will test positive...
Explain why the numerical value of the density of a substance will vary with the units of weight or mass and volume used, but the specific gravity of that substance will always remain the same.
5. Explain why direct antigen activation of CTLs and B cells is more important than APC-initiated activa- tion in subsequent encounters with a microbe. Why is the APC-initiated pathway needed at all? 6. There are many interactions between the innate and adaptive defense systems. List as many of them as you can and explain how they work. Why are these interactions important? Are all of them beneficial? 7. What are the two ways that polysaccharides, DNA, and lipid antigens can...
