Homework Answers
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 .
Add Answer to:
1. Define antibody and antigen.
2. Explain why immunoassays are consider to be vary specific

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...
