Keeping large cells in suspension

Hi All!

Has anyone found a way to keep large particles in suspension for
any extended period of time? The problem I am having is that I am
trying to sort a fraction of 100um particles and these things settle out
of solution after only 10 minutes or so. This makes the sort long and
tedious. I once heard about a food additive called xanthan gum that
would increase the viscosity of the liquid the particles are in. Does
anyone have this or another product working?

Thanks in advance.
