The simplest thing that comes to mind is the lysis by hypotonic shock. For
animal cells, this should be particularly easy (eons ago (at least that's
how it feels), I used to prepare rabbit retic this way). Freeze-thaw with a
very low molarity buffer (pH7.5?) may also be used (freezing in LiqN2 for
5min, follwed by thawing on ice ... repeated 2 to 3 times); This meth. works
very well for bacterial and yeast cells. In any case, lyses of cells do not
necessarily have to involve detergent(s).
