that may have occurred.
2. Describe how you would know that you had a “false positive” result. What does this mean for the rest of yourresults?
A positive result with a negative control indicates a “false positive” and yourresults are invalidated.

Describe how you would know that you had a “false positive” result. What does this mean for the rest of yourresults?
When there is a positive result that has a negative control, and it can invalidate all of the results.

2. Describe how you would know that you had a “false positive” result. What does this mean for the rest of yourresults? If it has a negative control then it’s a false positive so the results are invalidated.

fluorescence test to decrease the no-specific binding.
2. Explain where the epitope (antigenic determinant) is located.
The epitopes are located in the antigens for the antibodies binding.
3. Describe how a positive result is detected in this serological test.

molecular biology of the human immunodeficiency virus and the pathogenesis of acquired immune deficiency syndrome. The experimental concepts and methodology involved with enzyme-linked immune sorbent (ELISA) assays will be introduced in the context of the clinical screening of serum samples for antibodies...
Four kinds of ELISA here are here illustrated as you may concern:
(1) Direct ELISAs involve attachment of the antigen to the solid phase, followed by an enzyme-labeled antibody. This type of assay generally makes measurement of crude samples difficult, since contaminating proteins compete...
15. Transfusion Therapy
The immune system has evolved as a highly specialized function of human beings and is concerned with the substances considered “foreign” to the body.
It consists of a cellular component and a humoral component. Although...
Proteins are polymers of L-alpha amino acids : Proteins are linear, unbranched polymers constructed from 20 different L- alpha amino acids. These common amino acids are defined as those for which at least one specific codon exist in DNA genetic code. There are 20 amino acids for which DNA codons are...

- dual nature since it’s both a basic and applied science thus clin chem. technologists & technicians should have an understanding of the physiologic & biochemical processes occurring in the body, as well as technical skills to perform the various tests
therapeutic serum, toxin, antitoxin or analogous product
• includes the immunizing biologics that are derivatives of animals (serums, antitoxins, globulins) or of microscopic plant organisms (vaccines, toxins, toxoids, tuberculins) which either directly or indirectly confer a state of protection

interaction of antibody and antigen.
For this experiment, antibodies will be placed in wells on an agar plate, surrounded by wells containing serum (proteins, antigens etc.). If the antibody interacts with the antigen of surrounding wells, then the presence of a precipitate band will form and will...
identification of Proteins assayed From Bovine Liver Using SDS Gel Electrophoresis, Mass Spectroscopy and Western Blotting
The purpose of the experiment was to isolate and recognize varying protein solubilization and assaying methods by using bovine liver protein. The experiment implicated...
Protecting Our Children
Immunizing your children has become a hot topic among parents lately. Why would any responsible parent ever want to harm their child? By these so called responsible parents skipping their children’s schedule of immunizations they are introducing their children to some of the...
Then a solution which contains the non reactive protein like casein or the bovineserumalbumin is introduced to stop any further changes that had not drawn the interest protein, which is called the blocking step. Next the serum is introduced on which is known to contain the antibodies that is special...
