With the in-depth understanding of the cell culture process and the continuous improvement of technology, we can foresee that the application of fetal bovine serum in cell culture will be more precise and efficient. Generally speaking, the preparation of fetal bovine serum involves the following steps: First, select a fetal bovine of appropriate species and source. Generally, blood is collected from a healthy fetus with a good immune status. After collection, the blood is placed in a sterile container and the serum is separated by centrifugation or other methods. Next, the serum is sterilized, usually by filtering or heat treatment to ensure its quality and sterility. Finally, the treated fetal bovine serum is packaged and stored for future use.
