Detailed explanation-1: -An antigen is a foreign substance that enters your body. This can include bacteria, viruses, fungi, allergens, venom and other various toxins. An antibody is a protein produced by your immune system to attack and fight off these antigens.
Detailed explanation-2: -Antibody binding proteins such as Protein A and Protein G are often used in antibody purification and in applications such as immunoprecipitation (IP) and chromatin immunoprecipitation (ChIP). Each antibody binding protein varies in its ability to bind to antibodies of different subtypes and species.
Detailed explanation-3: -The antibody recognizes a unique molecule of the pathogen, called an antigen. Each tip of the “Y” of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision.
Detailed explanation-4: -An antibody is a protein component of the immune system that circulates in the blood, recognizes foreign substances like bacteria and viruses, and neutralizes them.
