3.25 in. x 4 in. Lantern Slides, Original Magnification: x20,000, and This was the first study to use immuno-EM to localize secretory proteins in pancreatic acinar cells. It showed that the RER cisternae, all compartments of the Golgi and all zymogen granules contained trypsinogen. We also demonstrated that trypsinogen was much more concentrated in zymogen granules than in the earlier compartments on the secretory pathway.

Description:
3.25 in. x 4 in. Lantern Slides, Hemoglobin, used as a tracer, is seen in the lumen of a capillary lined by a continuous endothelium, in endothelial caveolae, and in the extracellular space. Tracers such as hemoglobin or small heme-peptides were used by these investigators to demonstrate the role of caveolae in transcytosis of molecules across continuous capillary endothelial cells., and Original Magnification: x84,000
