Detailed explanation-1: -What are antibodies? Antibodies are proteins that protect you when an unwanted substance enters your body. Produced by your immune system, antibodies bind to these unwanted substances in order to eliminate them from your system. Another word for antibody is immunoglobulin.

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: -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.

Detailed explanation-4: -An antibody’s function in the immune system is to specifically bind and eliminate foreign particles. Antibodies may remove foreign antigens through several mechanisms. Neutralization-Antibody binding serves to neutralize foreign particles preventing interaction with cells and consequent cellular damage and invasion.

Detailed explanation-5: -B lymphocytes produce antibodies-proteins (gamma globulins) that recognize foreign substances (antigen) and attach themselves to them. B lymphocytes (or B cells) are each programmed to make one specific antibody.
