What is a recombinant clotting factor product?

Ultra High Tech!: These products(which are used to treat a wide variety of bleeding disorders like hemophilia, and von willebrand's disease) are made either by being completely free of human plasma derivative; or use a pasteurized form that is very safe. These products are not without there share of risks; and can potentially cause diseases as well. They are also very, very expensive so let the buyer beware!

Bacteria: Scientists get harmless bacteria to produce the proteins for us. The bacteria become like a factory after their genes get "recombined" in certain ways. Previously we had to get proteins from live animals and that was a problem for several reasons including inefficiency and exposure to animal viruses.
