Protocol – Feeding Suspension Culture (Complete Replacement of Medium)
Complete replacement of culture medium from suspension culture involves cell harvesting by centrifugation and resuspension of the cell pellet in fresh growth medium. This method is ideally the best way to feed suspension culture and is often used when a. you observe dead or sick cells/suspended particles in culture; b. medium color (phenol red-containing medium) has turned yellow very quickly; c. you can not afford cell loss. Complete replacement of culture medium is ideally the best way to feed suspension culture. Since this procedure takes time and involves an additional centrifugation step to harvest cells, often researchers partially replace the medium that takes just a few minutes. However, partial medium replacement is associated with the loss of cells from the culture.
