thereafter , the anisotropy of dph- and 12-as-labelled cells rapidly decreased ( 0.18 and 0.12 after 5 min ) , while that of tma-dph-labelled cells changed only slightly ( 0.27 after 30 min ) , suggesting that dph and 12-as , unlike tma-dph , do not remain anchored in the hela plasma membrane , but translocate to more fluid environments inside the cell .
