i want to wash cell biomass with sterile distilled water to remove media attached to the cells. For this, im thinking of using centrifugation at 5000rpm for 10 mins using distilled water and repeat it for 2-3 times. will this process cause cell disruption? will it result into loss of peptide /proteins from the cell biomass? If yes, can you please suggest me an alternative method for washing cell biomass effectively?
