High resolution image of quick-freeze deep-etch rotary-shadowed replica of an early endosome with two clathrin-coated evaginations. Presumably these coated pits contain receptors for cargo that will be pinched off from the early endosomes and passed on through carrier vesicles to the late endosomal compartments. Early endosomes lie at the level of the intraciliary lattice and proximal ends of basal bodies, but internal to the striated bands. TEM taken on 6/4/91 by R. Allen with Zeiss 10A operating at 80kV. Neg. 19,800X. Adapted with permission from J. Cell Sci. The raw film was scanned with an Epson Perfection V750 Pro. This image is best used for quantitative analysis.
