An antibody, also known as an immunoglobulin, is a large Y-shaped protein used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a unique part of the foreign target, termed an antigen.Each tip of the "Y" of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly (for example, by blocking a part of a microbe that is essential for its invasion and survival). The production of antibodies is the main function of the humoral immune system

What is a viral marker?
The viral marker DNA tells us whether or not a suspect (of a crime) is infected with any infections/viruses. If they are contaminated, then the results will not match up to those of the crime.
What is Rubella?
Rubella IgG is a specific antibody which our body's defenses has produced in response to a prior exposure, in this case, the virus Rubella.
How do you classify a virus?
Nature of the nucleic acid in the virionSymmetry of the protein shellPresence or absence of a lipid membraneDimensions of the virion and capsid
What is virus induction?
The interferon (IFN) system is an extremely powerful antiviral response that is capable of controlling most, if not all, virus infections in the absence of adaptive immunity. However, viruses can still replicate and cause disease in vivo, because they have some strategy for at least partially circumventing the IFN response.
The cold virus causes disease when it enters the of the human body?
Respiratory tract
Will an antibody produce against the influenza virus lock onto a common cold virus?
No because an antibody is produced for that specific pathogen. An antibody produced against influenza will not lock onto a common cold virus because the binding site on the virus is different compared to that of an antibody.
Are chickenpox antibody and shingles antibody the same?
Chickenpox and shingles result from the same virus, and generate the same antibodies. There is no difference between chickenpox antibody and shingles antibody, and there is only one test (varicella virus antibody) for both.
Is antigen a form of virus?
No. An antigen is something that an antibody will inactive. It is an antibody inducing agent.
Can antibody to mouse hepatitis virus transfer disease?
no
What protein can defend against a virus?
You are thinking of an antibody.
How is the AIDS antibody used for blood screening?
Basically the test is to check for the HIV antibody and NOT the HIV virus itself.
What is antibody and what you is the function?
Antibody is a type of protein produced by the immune system, its function is to fight antigens (bacteri, virus)
How do you classify viruse?
Virus is classified based on four characteristics. They are dimensions of capsid and virion, absence or presence of envelope, symmetry of capsid and nature of nucleic acid.
Can an antibody help fight off the flu virus?
Yes.
What characteristics does an abnormal Epstein-Barr virus test have?
The results for current or recent infection are: antibody to EA = positive, antibody to VCA IgM = positive, antibody to VCA IgG = positive, antibody to EBNA = negative.
What characteristics does a successful Epstein-Barr virus test have?
The results for susceptibility are: antibody to EA = negative, antibody to VCA (either IgM or IgG) = negative, antibody to EBNA = negative.
What does medical code 86790 mean?
Antibody; virus, not elsewhere specified
