Richard Allen (2011) CIL:12330, Euplotes sp., cell by organism, eukaryotic cell, Eukaryotic Protist, Ciliated Protist. CIL. Dataset

Euplotes sp. (eurystomus ?) is a hypotrich. This ciliate has a few rows of dorsal cilia as well as specialized clumps of cilia called cirri on its ventral side and a complex of membranelles involved in feeding called the adoral zone of membranelles. The cell is flattened dorso-ventrally. This electron micrograph is a longitudinal section dividing dorsal from ventral parts of the cell and exposing the oral cavity, the thread-like macronucleus, the extended contractile vacuole, contractile vacuole pore, and a large assortment of food vacuoles many of which contained material that was lost during sectioning leaving holes in the section. The cytopharynx and nascent food vacuole along with the discoidal (pharyngeal) vesicles are also seen. TEM taken on 8/3/67 by R. Allen with Philips 200 operating at 60kV. Neg. 1,370X. Bar = 5µm. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol, and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution version of this image is in the library (CIL:38867) and is available for quantitative analysis. Additional information is available at (http://www5.pbrc.hawaii.edu/allen/).

欧普洛特斯属（eurystomus？）是一种低毛类纤毛虫。该纤毛虫在其背侧具有几排背毛，以及在腹侧具有被称为触手的特殊毛簇，同时还有一个复杂的膜状结构，称为膜片进食区。细胞在背腹方向上呈扁平状。此电子显微镜照片为纵向切片，将细胞的背侧与腹侧部分分开，暴露出口腔、线状的大核、延伸的收缩泡、收缩泡孔以及大量食物泡，其中许多食物泡在切片过程中丢失了物质，导致切片上出现空洞。细胞咽和初生食物泡，以及圆盘状（咽部）囊泡也清晰可见。该透射电镜照片于1967年8月3日由R.艾伦使用Philips 200型仪器在60kV的电压下拍摄。负片放大倍数为1,370倍。使用标准戊二醛固定，随后用四氧化锇处理，经酒精脱水，并嵌入环氧树脂中。显微切片厚度约为75纳米。负片的打印件已被扫描并使用Photoshop进行处理。此图像最适合进行定性分析。该图像的高分辨率版本存放在图书馆中（CIL:38867），可供进行定量分析。更多信息可访问（http://www5.pbrc.hawaii.edu/allen/）。
