What is a poliomyelitis antigen?
Poliomyelitis antigen is a complex compound on the surface of the virus.
Virus bacterium or toxins that the body regards as foreign is known as?
antigen
An invading foreign material such as that on a virus is an?
antigen
What antibodies are tested for by Selectogen I and II?
Selectogen I tests for IgG antibodies to hepatitis A virus, hepatitis B virus core antigen, and hepatitis B surface antigen. Selectogen II tests for IgG antibodies to hepatitis C virus, hepatitis B core antigen, and hepatitis B surface antigen.
What is the difference between soluble and particulate antigen?
A soluble antigen is a viral antigen that remains after the virus has been removed. A particulate antigen is produced by particles such as dust and germs.
What on a virus stimulates the body's production of antibodies?
An Antigen.
What is an antigen made of?
An antigen may be made of either a bacteria or a virus. An antigen refers to a toxic or a foreign substance that once in the body attracts and is bound to a respective and specific antibody.
Why do virus infect us even its dead?
they have antigen properties after killing
What is injected in a vaccination?
Vaccinations typically contain a small, weakened, or inactivated form of a virus or bacteria, or a piece of the virus or bacteria, known as an antigen. This antigen stimulates the immune system to produce a response and build immunity against the targeted disease, without causing the disease itself. Other components in a vaccination may include preservatives, stabilizers, and adjuvants.
What is the difference between hepatitis B surface and hepatitis b antigen?
When your body is introduced to the Hepatitis B virus, the virus is considered the antigen (the surface antigen)and this should trigger your immune system to develop antibody against this antigen to destroy it. Most people do develop Hep B surface antibody when infected with the Hep B virus. Some people do not develop the antibodyand go on to have only circulating Hep B surface antigen - which means they are a carrier and can continue to have the virus and infection. For the majority of the population that develop the Hep B surface antibody, this conveys immunity to the virus for life.
Hemagglutination-inhibition test description?
It is the measures of the ability of soluble antigen to inhibit the agglutination of antigen-coated red blood cells by antibodies. In this test, a fixed amount of antibodies to the antigen in question is mixed with a fixed amount of red blood cells coated with the antigen (research on passive hemagglutination). Also included in the mixture are different amounts of the sample to be analyzed for the presence of the antigen. If the sample contains the antigen, the soluble antigen will compete with the antigen coated on the red blood cells for binding to the antibodies, thereby inhibiting the agglutination of the red blood cells.
What is hepatitis virus tests?
These tests are based primarily on antigen-antibody reactions--an antigen being a protein foreign to the body, and an antibody another type of protein manufactured by lymphocytes (a type of white blood cell) to neutralize the antigen.
