My experiment involves pulling down cells on to a filter plate for a variety of assays. However, I want to ensure that my cells are alive so I am trying to resuspend them so that I can do an accurate cell count. However, I am unable to close off the mass-balance which suggests that the cells are either getting through the membrane or getting stuck.
Any suggestions on the appropriate way to fully resuspend cells? I'm currently using a P200 to mix the solution.
