using quantitative immunogold electron microscopy and membrane length measurements , we showed lateral nonhomogeneity of receptors in the membranes of trans-golgi reticulum and curl , in particular in the membranes of secretory vesicles ( identified by their content of albumin and very low density lipoprotein particles ) and of curl vesicles ( endosomes ) , including multivesicular bodies .
