-       Allow the media to warm for about one hour in the 37ºC water bath.
-       Cells frozen in DMSO can be thawed by gently shaking by hand in the water bath.
-       Gently remove cells from tube with 1mL pipette and transfer to P10.
-       Add 10 mLs of media (above)
-       Place in incubator
-       The following day, remove old media and replace with new to remove remaining DMSO

-Trypsin should be diluted 4X!

Example:   For 5mls use 1.25mls Trypsin with 3.75mls HBSS

-Remove the media and add ½ amount of 4x diluted trypsin as the total amount of media removed.  If the cells are on a P10 and 10mls of media was removed add 5mls of trypsin + HBSS
