Capture and detection antibodies must recognise two non-overlapping apitopes in order to work. Once the detection antibody is bound, the capture antibody cannot obscure the epitope used by the detection antibody in any way, or the sandwich ELISA will not work. Hope that helps, I am also trying to answer a similar question and this is what i have found out so far, but not 100% sure that its right. Eve
B cells make antibodies when they recognize antigens.
Antibodies recognize antigens by binding to specific molecules on their surface. This binding triggers a series of events that activate the immune response, including the production of more antibodies and the recruitment of immune cells to destroy the antigen.
Yes, B cells have antibodies on their surface that help them recognize and bind to specific antigens.
Simple the answer is an Antibody!
Antigens
The constant regions of antibodies (Fc regions) primarily determine the antibody's class and are involved in mediating immune responses, such as binding to Fc receptors on immune cells. They do not vary significantly between different antibodies of the same class, unlike the variable regions that recognize specific antigens. Therefore, a statement claiming that the constant regions vary greatly among different antibodies would not be true.
Our bodies do have the ability to make antibodies to something we never have had contact with. These are called natural antibodies. Natural antibodies are produced by B lymphocytes in the absence of external pathogen stimulation. With their ability to recognize between self and non-self, they comprise an important first-line defense. Any problem with this formation of natural antibodies, the body would begin to attack itself. This is seen in autoimmune disorders.
When antibodies bind to the epitopes of an antigen(bacteria) via antigen receptors, the antibodies present the bacteria to a macrophages in a form that they recognize the foreign substance and engulf them. This antibody-antigen "team work" is also known as opsonization
There are 5 different types of white blood cells and all produce antibodies as a function of immune response. The five types are neutrophils, esoinophils, basophils, lymphocytes, and monocytes. They all respond to different threats to our body's health.
Antibodies are made by a type of white blood cell called B cells. When the body detects the presence of a foreign substance (antigen), B cells are activated to produce antibodies specific to that antigen. These antibodies work to help the immune system recognize and eliminate the invader.
God has sent each and every people with same physique but with different mindset. And it is therefore important to recognize and honor one's role,struggle and contribution in life.
It is important to recognize the author's tone.
