Adherent NK cells: No trypsin please!

I was of the understanding that adherent NORMAL NK populations lost 
their adherence rather quickly (24-72 hours), yet retained the 
phenotype of NK/LAK cells - see the publications of John Hiserodt of 
the early '80's on ALAK culture and purification.
Hope this helps-
