What is the different between polyclonal antibody and antiserum?
polyclonal antobody is the antibody produced for many or non specific antigens but antiserum is the antibody for a specific antigen
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.
What are the differences between indirect ELISA and sandwich ELISA?
Indirect ELISA and sandwich ELISA are two types of enzyme-linked immunosorbent assays used in laboratory testing. In indirect ELISA, the antigen is immobilized on the surface, and a primary antibody binds to the antigen. Then, a secondary antibody linked to an enzyme is added to detect the primary antibody. In sandwich ELISA, the antigen is captured by a primary antibody that is immobilized on the surface. A second antibody linked to an enzyme is then added to bind to a different epitope on the antigen, forming a "sandwich" complex. The main difference between the two methods is the way in which the antibodies are used to detect the antigen. In indirect ELISA, the primary antibody is detected by a secondary antibody, while in sandwich ELISA, the antigen is "sandwiched" between two antibodies for detection.
What is the relationship between antigen and antibody?
Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
Why do you need a different antibody for each type of cell?
Because every cell subject to attack by antibodies has different antigen components on its surface, displaying different " locks " to the antibodies " keys. " This is why a form of selection is used in generating a wide variation in antibody CDR sites.
How are immunizations and immune globulin different?
immunization is the antibody giving to the human to get the immunity. but immun globulin is existing antibody in the human body.
Are the genes coding for one antibody entirely different from those coding for a different antibody?
no, not entirely. Each antibody (Immunoglobulin, "Ig") has both 2 constant regions referred to as "heavy hains" and 2 variable regions referred to as "light chains". The structure of the heavy chains remain the same between the different antibody structures. However, the light chains differ in structure enabling them to respond differently to different specific antigens introduced to the cellular membrane.
What does allergen antibody react?
they react with different blood types!
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.
What is the reaction between antibody and particulate antigens called?
agglutination reaction
What is the difference between alloimmunization and isoimmunization?
the autoimmune reaction is the reaction between the antibody and antigene when both come from the same body but the isoimmune reaction is between the antigene and antibody produced for the same antigene ( the same according to the type but not the immunity )
Define and distinguish antibody affinity and avidity?
An antibody (IgM for example is a pentamere), can consist out of more than one different immonoglobulines. One of the variabel regions of these immunoglobulines can bind to an epitope of an antigene, this is called affinity. When different variabel regions of one antibody bind to different epitopes on an antigene, the combined effect is called avidity. The effect is not equal to the sum of the affinity's.
