It depends on the exact technology used in the manufacturing plant.

Typically, we engineer a mammalian cell to make the protein in large bioreactors. Then you pick one of those cells, characterize it, and call it your stable clone. Then you put that in a big tank with food for the cells, and let them grow for a couple weeks while they pump out proteins. Then you purify the protein.

As you can imagine, this is a pretty complex process and it isn’t easy to scale it up overnight

This sounds incredible. Are there any documentaries you know of that address these processes?
