cell permeabilization

You could try the "osmotic lysis of pinocytic vesicles" method first described
by Okada & Rechsteiner (1982), CELL 29:33-41. The method is based on
pinocytosis of your protein from a hypertonic medium, and then "crushing" the
vesicles in hypotonic medium. The method is just now being commercialized by
Molecular Probes as the "Influx Cell-Loading Reagent" (no affilitation).
I have not tried the method yet, but it sounds VERY promising, so I´m planning
to use it in the next future. 

Hope this helps,
