-The first antibody is specific for the primary amino acid sequence of TT, whereas the second is specific for conformational determinants.

Explanation;

-Antigen-antibody reaction, is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction.The specificity of the binding is due to specific chemical constitution of each antibody.
