Verified step by step guidance

Understand the context: Antibodies are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.

Identify the key term: The problem asks for the specific part of the antigen that antibodies bind to.

Define the term 'Epitope': An epitope, also known as an antigenic determinant, is the specific part of an antigen that is recognized and bound by an antibody.

Differentiate from other terms: Isotype refers to the class of an antibody, hapten is a small molecule that can elicit an immune response only when attached to a large carrier, and paratope is the part of the antibody that recognizes the epitope.

Conclude with the correct term: Based on the definitions, the specific part of the antigen that antibodies bind to is the 'Epitope'.
