MHC @ trypsin

[David R. Johnson]

Alec-

MHC class I molecules on the surface of cultured cells are RESISTANT to
trypsin treatments used to suspend the cells.  I do this routinely to
study expression by FACS.  Purified MHC class I molecules are sensitive
to relatively large amounts of trypsin.  Sorry I cannot cite a reference
off the top of my head, but it has been shown by different groups.

I hope this helps.
