What else can I help you with?
Can any antibody work with any antigen?
No, not all antibodies can work with any antigen. Antibodies are highly specific in recognizing and binding to a particular antigen based on their unique binding sites. The binding of an antibody to an antigen is based on complementary shapes and charges, so a specific antibody will only bind to a specific antigen that matches its binding site.
How do protein A and protein G differ in their ability to bind to specific antibodies?
Protein A and protein G differ in their ability to bind to specific antibodies based on their binding preferences. Protein A primarily binds to antibodies from the IgG class, while protein G has a broader binding range and can bind to antibodies from multiple classes, including IgG, IgM, and IgA.
How do antibodies recognize antigens and initiate an immune response?
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.
What is a protein thatacts against a specific antigen?
An antibody is a protein that acts against a specific antigen by binding to it and marking it for destruction by the immune system. Antibodies are produced by B cells in response to the presence of foreign substances in the body.
What is the best definition for antibodies?
Antibodies are proteins produced by the immune system in response to the presence of foreign substances, like viruses or bacteria. They help to identify and neutralize these invaders by binding to specific molecules on their surface.
Which of the following initiates an attack against a specific antigen or pathogen?
Plasma Cell initiate attacks against specific antigens. Plasma cells are B cells bearing specific antibodies for binding to a specific antigen.
An antigen is a substance that produces?
An antigen is a substance that produces an immune response in the body, typically by binding to specific antibodies or activating immune cells. This immune response is essential for recognizing and eliminating foreign substances such as pathogens.
A method of tagging antibodies with a fluorescent dye to detect or localize antigen-antibody combinations is known as?
Immunofluorescence staining. This technique involves binding a fluorescent dye to antibodies, which can then be used to detect and visualize specific antigens in a sample.
Antibodies can stick to?
Antibodies stick to any viruses or infections. They don't attack, but they are like homing devices. They track the diseases so white blood cells (the attackers) know where the diseases are.
What pathogens respond to antibodies?
Pathogens such as bacteria, viruses, fungi, and parasites can respond to antibodies produced by the immune system. Antibodies work by binding to specific antigens on the surface of pathogens, marking them for destruction by other immune cells. This antibody response is a key component of the adaptive immune system's defense mechanism against infections.
What are Antibodies are composed primarily of amino acids what class would antibodies belong?
Antibodies are proteins, which are macromolecules composed primarily of amino acids. They belong to the class of biomolecules known as globular proteins, characterized by their complex three-dimensional structures that enable specific binding to antigens. Antibodies play a crucial role in the immune system by identifying and neutralizing pathogens.
Why are electrophoretically fractionated proteins transferred to a membrane for detection?
Proteins are transferred to a membrane for detection after electrophoretic separation in order to facilitate detection of specific proteins using antibodies. This technique, known as Western blotting, allows for the visualization and quantification of target proteins by binding specific antibodies to the transferred proteins on the membrane.
