Scientists compared two methods of producing an antibody that binds to one protein antigen. The table shows their results.
Table: The cells used in two methods of producing an antibody and the mass of antibody produced by each method after 10 days
| Method | Cells used | Mass of antibody produced after 10 days in mg |
|---|---|---|
| A | lymphocytes taken from a mouse, grown on their own | 0.4 |
| B | cells cloned from a single hybridoma cell | 96.0 |
Calculate how many times greater the mass of antibody produced by method B is than the mass produced by method A.
Explain the difference in the mass of antibody produced by the two methods.
The antibody produced by method B is a monoclonal antibody. The antibody produced by method A is not. Explain why.
