I somewhat understand that some monoclonal antibodies are developed from the cells of mice, or a fusion of human and mice genes.
When something is a fully human monoclonal antibody does that mean it came from some person? What type of human cell did it come from? Will the drug always be from that original human?
I read that they're derived from something called a phage display technique. I'm guessing this is another type of way to fuse genes together, but with all human cells.
Where do the cells come from?
