What is a monovalent antigen?
A monovalent antigen is a type of antigen that contains only one type of epitope, which is the specific molecular structure that can be recognized by the immune system. This means that the antigen can only trigger a response from one type of antibody.
Which of the following is NOT true about antibodies a. an antibody has more than one antigen binding site b. a pathogen can have different epitopes c. a pathogen makes more than one antigen?
c. a pathogen makes more than one antigen. Pathogens typically have multiple epitopes that can be recognized by antibodies, but they do not make more than one antigen. Each pathogen produces specific antigens that can trigger an immune response.
What is a xenoantigen?
A xenoantigen is an antigen which is found in more than one species.
How do antibodies destroy pathogens?
binding to antigens on the pathogens.The antibodies not only bind to antigens...but once bound with the antigens on the viruses they encounter. The viruses clump together and are destroyed by phagocytes.Thanks to...my BRILLIANT mind!! :PYOU ARE THE BEST!
What is a substance that the body regards as foreign?
One term that is used is antigen. An antiGEN will GENerate an ANTIbody which will 'kill' the antigen.
Can an antibody produced to fight against one antigen fight against a different antigen?
true
Don't Rh factor is an Antigen that can cause problems in some women who bear more than one offspring true or false?
yes. you must be doing your human anatomy in Aplus too lol
What does genotype cDEcde indicate?
The genotype cDEcde indicates that the individual carries one copy of the C antigen, one copy of the c antigen, as well as one copy of the E antigen and one copy of the e antigen. This genotype is related to the Rh blood group system.
Difference between monoclonal antibody and polyclonal antibody?
Polyclonal antibodiesMonoclonal antibodiesInexpensive to produceExpensive to produceTechnology required is lowHigh technology requiredSkills required are lowTraining is required for the technology useTime scale is shortTime scale is long for hybridomasProduces large amounts of non specific antibodiesCan produce large amounts of specific antibodies but may be too specificRecognizes multiple epitopes on any one antigenRecognizes only one epitope on an antigenCan be batch to batch variabilityOnce a hybridoma is made it is a constant and renewable source and all batches will be identical
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.
What should be done if some one suffer from Australia antigen reactive?
Can patient of Australia Antigen have the physical relationship with spouse.
What is linked recognition?
Linked Recognition occurs when a B cell is activated by a helper T cell that responds to the same antigen as the B cell. The epitope recognized by the B cell must be "linked" to the epitope recognized by the helper T cell--in a manner such that both epitopes are physically linked in a certain manner. However, the two epitopes need not be the same. The importance of linked recognition can be observed in maintaining self tolerance. Also, a B cell recognized by a helper T cell is up to 10,000 times more efficient at displaying peptide fragments on their MHC class II molecures than B cells that are not helped.
