Transfection of proteins into cells: HOW?

[Stefan Kahlert]

I want to block proteins in cells with specific antibodies,
and I'm looking for possible methods to get this antibodies
into these cells.
Problems:
 
- microinjection is not possible because I work with suspension cells
  (hard to catch and even harder to find the injected ones to check
  the result)
 
- electroporation is *not* the way to (please don't ask why. The story
  is to long to be told here I think).
 
What other methods are possible to get antibodies or other proteins into
suspension cells?
 
Thanks in advance
 
Stefan
