Hi. I need some help. I need to so size exclusion chromatography on samples, but they have flocculent which sediments upon standing. Im assuming it will not be practical to add such sample to the gel bed as the floccule may reside there and not permeate through. The reason for the flocculation is the addition of chitosan wich then surounded the liposomesso the sediment is actually importany because there may be liposomes in it. I am not sure what to do as im afriad filtering would leave me with no nanoparticles?
