No. Hapten is an antigen whic has low molecular weight and does not trigger immune system.
The antigens cause an immune response leading to production of antibodies thereby causing the host to be resistant to subsequent infection
Antigen is a substance that can induce the generation of antibodies, any substance that can induce immune response. Antibody is a protective protein produced by the body in response to an antigen.
Antigens are substances that trigger an immune response, typically because they are recognized as foreign by the immune system. They can be proteins, polysaccharides, or other molecules found on the surface of pathogens like bacteria, viruses, or fungi, as well as on pollen, toxins, and even transplanted tissues. When the immune system encounters an antigen, it produces specific antibodies and activates immune cells to eliminate the threat. This process is crucial for protecting the body against infections and diseases.
Antigens are actually molecules that trigger an immune response in the body by activating the production of antibodies. Free radicals are unstable molecules that can cause damage to cells and are often neutralized by antioxidants, not antigens.
Antigens, by definition, cause the body to produce antibodies which act against them. You inherit certain antigens which are on your red blood cells. Sometimes these antigens are absent from your RBC. If you are type B, you have B antigens. Type A has A antigens, AB has AB antigens and type O has no antigens. If you are type AB, you can receive AB blood from some one else.
Antigens are surface membrane molecules that cause an immune reaction.
no it does not cause fermentation. What do you mean by an Antigen in the context of fermentation? Zymase is the enzyme used in fermentation, when this enzyme used as an Antigen to immumize an animal, it do produce antibody against it :)
Because they are seen as pathogen invaders by the immune system.
Vaccines take advantage of the body's immune system's way of fighting pathogens. When your body is exposed to some pathogen, which has various antigens on its surface, the immune system would start making antibody against those antigens. Normally, it would take sometime for your body to response with first exposure. Subsequence exposures would result in much more rapid response. Vaccines work by isolating these antigens and give it to you exposing the immune system. You should not get the disease, since only the antigens are given instead of the full pathogen. Sometimes, it may be difficult to completely separate the antigens, so they weaken to pathogens to the point that they would not cause the infection in healthy individuals. These are call live attenuated vaccines. Exam of these are MMR, Varicella Vaccines, Flu mist.

Yes, anything that triggers your immune system to have a response would be considered an antigen. H1N1 is a virus that causes influenza, and the detection of the presence of the virus will cause our immune systems to attack it. The immune system creates antibodies which can grab antigens to flag them as targets and disable them, which are then attacked and destroyed by other cells from the immune system. Once the body has developed antibodies to match the antigens of a particular invader , the pattern of those antibodies is stored by the immune system, and duplicates can be readily produced to grab that invader, if it or one like it, is detected again. That is what gives you immunity.
The main cause of immune system disorder is expose of closed self antigens those were not recognised by body immune system's antibodies against these self antigens started to produced that combined with it and causes inflammations
