Proteins that recognize and bind to a particular antigen with very high specificity.
A
antigen
B
antibody
C
B cells
D
Lymphocytes
Explanation: 

Detailed explanation-1: -What are antibodies with high specificity (only detect one epitope) called? Monoclonal.

Detailed explanation-2: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.

Detailed explanation-3: -The amino acid sequence in the tips of the “Y” varies greatly among different antibodies. This variable region, composed of 110-130 amino acids, give the antibody its specificity for binding antigen. The variable region includes the ends of the light and heavy chains.

Detailed explanation-4: -The antigens and antibodies combine by a process called agglutination. It is the fundamental reaction in the body by which the body is protected from complex foreign molecules, such as pathogens and their chemical toxins.
