Try spinning your cell suspension over a Ficoll-Hypaque gradient.  I have successfully 
done this to clean up both hybridoma cells as well as preparations of activated cells.  
Cells harvested from the interface are usually 95-100% viable.
You will probably lose some cells in the process, so if cell numbers are crucial you may
want to try another method first.

Good luck!
