Why is the culture medium usually reddish?
Because phenol red is added as an indicator to the culture medium, indicating a pH range of 6-8, if the culture medium is acidic, it will turn yellow, and if it is alkaline, it will turn purple. It is necessary to change the medium in a timely manner and replace it with fresh culture medium to maintain a good growth environment for cells. Some special cells require phenol red free culture medium and need to be observed in a timely manner.
