Biopharmaceutical is the use of biotechnology to produce natural active substances in living organisms. Its effective ingredients are usually some bioactive proteins, DNA, viruses, cells or tissues, etc. the administration method is direct tissue injection.

Animal cell culture is to take relevant tissues from the animal body, disperse them into individual cells (using trypsin or collagenase), and then put them in a suitable culture medium to allow these cells to grow and proliferate.

When culturing a certain cell for the first time, you must first search the name of the cell to understand relevant information, including the culture medium, serum, additives, normal digestion time, passage time, etc. For specific cells (such as primary cultured cells), it is necessary to consult relevant literature to obtain more accurate culture methods.
