Nuclear pores in face view of Opercularia coarctata. TEM taken on 6/13/69 by R. Allen with Philips 300 operating at 60kV. Neg. 14,800X. Bar = 0.25µm. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:7341) is available for quantitative analysis. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness.
