Ficin is an enzyme that has a number of uses in several markets. As mentioned in the DESCRIPTION section of the product detail page, ficin from fig tree latex has been used:
in the proteolysis of tendon collagen (tendons are softened in meat/muscles)
in the digestion of Chlorophyta Ulva rigida (softens this algae which is used in 'sea salad' and animal feed)
to investigate it's effect on protease-activated receptors 2 and 4 activation to induce itch in skin (studies indicate it can cause itching)
in disrupting the staphylococcal biofilms, making it accessible antibiotics exposure. (Staph can be very resistant to antibiotics, particularly in 'biofilms'. Ficin digests or breaks down this film so that antibiotics are more effective.)
It is also used in the food industry, primarily dairy products and is useful in clotting milk to aid in cheese production.
Ficin has several medical uses, as well. This product is for research use only, however the link below describes some of the medical applications of Ficin:
