High resolution electron micrograph of a thin frozen section treated with a clone of the mAb (D40-2) used to show the A4 antigen on decorated tubules. The immunogold lies along the outer margin of the...

High resolution micrograph that shows the pegs on the surface of the decorated tubules that are negatively stained by the uranyl acetate dissolved in the methylcellulose solution used to give support ...

Immunoelectron microscopy of mammary gland tissue from lactating rats with the trans-Golgi network identified by immunogold labeling of TGN38, a transmembrane trans-golgi protein. Note that trans‐Go...

Immunoelectron microscopy of mammary gland tissue from lactating rats with the trans-Golgi network identified by immunogold labeling of TGN38, a transmembrane trans-golgi protein. Note that trans‐Go...

Immunoelectron microscopy of mammary gland tissue from lactating rats with medial cisternae of the Golgi apparatus indicated by immunogold labeling of MG-160, a 160 kDa membrane sialoglycoprotein spec...

A micrograph showing the polyploidal macronucleus of Tetrahymena containing many copies of the genome. Chromatin material is found as condensed electron opaque spots as well as in an uncondensed form...

Monoclonal antibody, E30-2-1, was raised to antigen D6 that specifically labels acidosomes and DV-II. There was no label on the nascent vacuole membrane or ciliary membranes. This cell had been incuba...

Ciliates such as Paramecium have specialized sites for endocytosis and exocytosis. Most of their surface is not available for internalization of membrane because of the underlying alveolar sac system....

High resolution view of the contractile vacuole pore encircled on its cytosolic surface with microtubules. Other microtubules arise from these encircling microtubules and extend far out into the cell ...

High resolution view of the quadrulus membranelle (4 rows of cilia) in the buccal cavity of Paramecium tetraurelia labelled for tubulin. Microtubules of the axonemes of the cilia and the triplet fiber...
