Answer;

-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.

-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.
