And that can be a very, very useful technique if actually used correctly. So the solution lies in using immortal plasma cells derived from a type of cancer known as multiple myeloma. So multiple myeloma is a specific type of cancer cell of plasma cells. So let's take a look at the following three steps in our procedure to mass produce these specific monoclonal antibodies. So, in step one, what we basically want to do is we want to find an organism with a healthy and functional immune system. So, for example, let's take a mouse.
