Richard Allen (2010) CIL:10249, Halteria grandinella, cell by organism, eukaryotic cell, Eukaryotic Protist, Ciliated Protist. CIL. Dataset

The DNA replication band in macronucleus of Halteria. Like hypotrichs the macronucleus of this oligotrich has a DNA replication band where DNA is synthesized. The nucleolus is evident. TEM taken on 3/9/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 13,750X. Bar = 0.5µm. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:7601) 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.

本描述涉及Halteria寡毛虫的巨核DNA复制带。类似地，该寡毛虫的巨核亦具有DNA复制带，其中DNA得以合成。核仁清晰可见。该透射电子显微镜（TEM）图像由R. Allen于1971年3月9日拍摄，使用的是75kV的日立HU11A仪器。负片放大倍数为13,750倍，标尺长度为0.5微米。负片打印件经过扫描和Photoshop处理。该图像适用于定性分析。高分辨率图像（CIL:7601）可供定量分析使用。采用标准戊二醛固定法，随后以四氧化锇处理，经酒精脱水，并嵌入环氧树脂中。微切片厚度约为75纳米。更多信息请参阅（http://www5.pbrc.hawaii.edu/allen/）。
