Concept explainers
To examine: Whether the statement, “Because a monoclonal antibody recognizes a specific antigenic site (epitope), it binds only to the specific protein against which it was made.” is true or false.
Concept introduction:
Monoclonal antibodies are the protein molecules, which developed in laboratory condition that particularly binds with the target antigens. Monoclonal antibodies are designed by the fusion of spleen cells that are modified with desired antigens and myeloma cells.
Answer to Problem 1P
Correct answer: The statement is false.
Explanation of Solution
Monoclonal antibodies have the capacity to recognize the specialized antigenic site, but it is not specific for a particular protein molecule. However, same antibody attaches with various antigens having antigenic similarities with different affinities. If in an assay, there are utilization of excess amount of antibody occurs, binding affinities of that specific antibody may differ according to the antigen. There are some proteins, which attaches to antibody with high affinity and others with less affinity.
Hence, the statement is false.
