Abstract:
Electron tomography can provide additional morphological information not easily obtained by conventional transmission electron microscopy of thin sections. It uses a goniometer stage in the electron microscope to tilt the specimen and collect a series of 2D images from different orientations, which are combined to provide a 3D volume tomogram and a colored reconstruction of the morphological feature(s) of interest. Here we describe the protocols for its use in visualizing changes in organelle morphology after depletion of the SNARE proteins VAMP7 and VAMP8 and to study VAMP7 localization on endolysosomes/lysosomes.

SNAREs and Membrane Fusion
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...
