Review Questions

• Explain the role of mice in the production of polyclonal antibodies.
  • Mice are commonly used as hosts for the production of polyclonal antibodies due to their well-developed immune systems and ability to mount robust immune responses to a wide range of antigens. When a mouse is immunized with a specific antigen, its B cells will produce a diverse array of antibodies, each recognizing a different epitope on the antigen. The serum collected from the immunized mouse contains this polyclonal mixture of antibodies, which can then be used for various research and diagnostic applications.
• Describe the process of generating monoclonal antibodies using mouse B cells.
  • The production of monoclonal antibodies using mice involves the following steps: 1) Mice are immunized with a specific antigen to stimulate the production of antibody-secreting B cells. 2) The antibody-producing B cells are isolated from the mouse and fused with immortalized myeloma cells, creating a hybridoma cell line. 3) The hybridoma cells are then cultured, and the resulting monoclonal antibodies are secreted into the culture medium. 4) The monoclonal antibodies can be purified and used for various applications, such as diagnostics, research, and therapeutic development, due to their ability to specifically recognize a single epitope on the target antigen.
