George E. Palade EM Slide Collection
The collection includes some of the earliest electron micrographs from Rockefeller University and Yale University. Many of the images are significant for their contribution to our understanding of cellular structure and processes. The images were used in the cell biology courses at Yale University by Drs. George Palade and Marilyn Farquhar. It was Dr. Palade's wish that the collection of images be freely available to students and scientists world-wide.
Immune Cells Rat myocardium plasma cell
This study examined the intracellular secretory pathway for IgG using tritiated leucine to tag the protein backbone and tritiated galactose and glucosamine to tag the glycoprotein chains synthesized in the Golgi. EM autoradiography was used to follow the travels of IgG after synthesis. The results indicated that IgG (the major protein synthesized by these myeloma cells) moved from the RER to the Golgi for sugar addition to IgG and likely reached the cell surface via small smooth surfaced transport vesicles. Previously it had been suggested that IgG moved in soluble form through the cytoplasm and was secreted directly through the plasma membrane. No evidence was obtained for temporary storage in secretory granules.
