Bovine alkaline growth factor eye drops, its main ingredient is a kind of alkaline growth factor. This growth factor mainly promotes mitosis and cell proliferation to restore the corneal or conjunctival epithelium to repair corneal or conjunctival epithelial defects caused by inflammation or trauma. In ophthalmology, it is mainly used in cases such as post-surgical inflammation or some trauma-induced corneal epithelial defects. Of course, this alkaline fibrogenic factor is unstable and needs to be kept in the refrigerator at about 2-4°C. If it is kept in a warmer environment, it will be more stable. If it is kept in a warmer environment, it will easily fail, so it is very important to preserve the alkaline fibroblast growth factor. Also pay attention to the properties, if the color changes, it should be activated in time, because it does not contain preservatives and is susceptible to various bacteria or external environment.
