The appearance of freeze-drye DNA depends probably on its molecular
weight: High molecular weight DNA will appear cotton-like, low
molecular weight DNA may be a powder. In hybridization experiments
fish sperm DNA is usually used to block reaktive points of the
membrane you use. So the molecular weight doesn´t really matter, if
the fish DNA-solution is to viscous, you even can sonicate it.
