Electron Microscopy Images
A variety of images from the scanning and transmission electron microscopes are available for viewing.These images are in the public domain. If you have questions about the images or the microscopy and specimen preparation used to obtain images contact Max Guinel.

Tissue culture cell line, infected with human immunodeficiency virus (HIV)
HIV particles are 90-120nm in diameter.
The process of infection: (1) virus attaches to the cell via the CD4 molecule on the surface of the cell. The CD4 molecule on the lymphocyte acts as a cell surface receptor for HIV. (2) fusion of the virus envelope with the host cell membrane. (3) nucleocapsid, containing the genetic material, is carried into cytoplasm by endocytosis. Instrument: JEOL 1010 TEM.

Transmission electron microscope image of a thin section cut through the bronchiolar epithelium of the lung(mouse), which consists of ciliated cells and non-ciliated cells. Image shows the ciliary microtubules in transverse and oblique section. In the cell apex are the basal bodies that are the anchoring sites for the cilia. Note the difference in size and shape between the microvilli and the cilia. At the basal end of the epithelial layer is the basement membrane. Instrument: JEOL 1010 TEM
