Accepted Answer

D

Question 2

Figure 21.2Using Figure 21.2, match the following:
-What are monoclonal antibodies? How are they produced, and what are some of their clinical uses?

Accepted Answer

Monoclonal antibodies are pure antibody preparations that exhibit specificity for a single antigenic determinant. They are produced from the progeny of a single B cell hybridoma "clone," prepared by injecting a specific antigen into a lab animal and then harvesting sensitized B cells from its spleen. The cells are mixed with myeloma cells and incubated, and the resulting hybridoma cells (B cells fused with myeloma cells) produce the monoclonal antibody. They are used for the diagnosis of pregnancy, certain sexually transmitted diseases, hepatitis, rabies, and for other purposes.
