Evaluate the differences between IgG and IgA antibodies in terms of their structure and primary function.

In a biochemical assay, why might a researcher choose to use monoclonal antibodies over polyclonal antibodies?

Analyze how antibodies are used in ELISA to detect the presence of specific antigens.

Evaluate the importance of the variable (V) region in antibody function.
