in a second approach , changes in diffusion coefficients of plasma membrane-associated macromolecules were determined by measuring the fluorescence redistribution after pulse photobleaching ( frap ) : individual plasma membrane proteins ( sigm , leu 12 or leu 16 ) were labelled with fitc conjugated goat antibodies [ f ( ab ' ) 2 or fab ' ] or with phycoerythrin-b conjugated monoclonal mouse antibodies .
