For your application you can probably use any of these methods, as you
are working with small amounts and do not require the maintainance of
subcellular structures. A small Potter or a sonicator are probably
easiest.
Just remember to keep everything on ice during homogenisation, as both
methods produce heat.
Add a mix of protease inhibitors (1 mM PMSF (fresh from 1000 times stock
in DMSO, toxic), benzamidine, EDTA and e-aminocaproic acid (100 uM
each), pepstatin and leupeptin (2 uM each)).
