Why IgM is normally the first antibody to be produced during any infection?
Wiki User
∙ 13y ago
A mature naive B cell expresses on its cell membrane as receptors IgM and IgD. When it finds a specific antigen, it will undergo several divisions and finally differentiation in memory cells and plasma cells. The genes that code for the IgM class are still present in the plasma cells, and therefore those are the types of antibodies that are first produced and released. However, later class switching occurs within those genes, and new types of antibodies with the same specificity are produced (IgG, IgE, IgA)

Are antibodies nonspecific?
Antibodies are non specific! That is why antibody testing does not signify anything specific except that an immune response is on progress. Processed flour will give you an immune response and show elevated liver enzymes that are typical during times of infection
What is the first antibody made in response to an antigen?
IgM is the antibody first secreted during primary response
How does blood infected with bacteria differ from healthy blood?
More white blood cells are produced during an infection
A clumping of antigen-to-antibody particles during an immunoassay such as the modern pregnancy test is known as?
agglutination
How is mononucleosis diagnosed?
Mono tests include:• Monospot test. This quick screening test detects a type of antibody (heterophil antibody) that forms during certain infections. A sample of blood is placed on a microscope slide and mixed with other substances. If heterophil antibodies are present, the blood clumps (agglutinates). This result usually indicates a mono infection. Monospot testing can usually detect antibodies 2 to 9 weeks after a person is infected. It typically is not used to diagnose mono that started more than 6 months earlier.• EBV antibody test. For this test, a sample of blood is mixed with a substance that attaches to antibodies against EBV. A series of tests can detect different types of antibodies to help determine whether you were infected recently or sometime in the past.
WhAT skin infection is common during adolescens?
The skin infection that is common during adolescence is called acne.
Can pid be caused by a bacterial infection during pregnancy?
PID can be caused by a bacterial infection during pregnancy.
What might you see if refraction occurred during precipitation?
If refraction occurs during precipitation, it is possible that a rainbow will be visible after the storm. Rainbows are produced when the eye can actually see the bending of light rays that is not normally visible.
What sugar produced during photosynthesis?
The sugar produced during photosynthesis is glucose.
What energy carrier is produced during glycolysis?
There are a few energy carrier produced during Glycolysis but NADH and ATP are most produced.
Why limiting dilution is used in hybridoma technology?
limiting dilution is a method used to have a single cell / well in a tissue culture plate. and why we need a single cell / well ...to ensure that we have single clone of antibody producing B cell as during any immuneresponse a mixed of different B clone will produce to make antibodies against foreign antigen even during the 2ndary immune response the antibodies produced will have different structure in the variable region because of somatic hypermutation process during affinity maturation at the germinal center. Thus, we do a limiting dilution to study each B cell clone antibody produced individually and test its specificity by ELISA, which can be easy to detect the best affinity binder clone and chose it for further steps.
What is produced by yeast during fermentation?
Carbon Dioxide (C2O) and Alcohol are produced by yeast during fermentation.
