How many days to change the culture medium?
Under normal circumstances, the culture medium tends to be red. If the cells are maintained at pH 6.5-6.6 and the culture medium turns yellow, it indicates that metabolic products have accumulated to a certain amount in the culture medium, and the cells will fall off and die, requiring replacement with fresh culture medium. Generally, when cells grow vigorously, they should be replaced every 1-2 days. When growth is slow, it can also be replaced every 3-4 days.
