Gregory Antipa (San Francisco State University) (2011) CIL:25688, Trichodina, Chlorella, cell by organism, eukaryotic cell, Eukaryotic Protist, Ciliated Protist. CIL. Dataset

Cytoplasm of a green Trichodina that lives on the surface of a freshwater snail collected in central Illinois. In this view the abundant endosymbiotic zoochlorellae and a single endosymbiotic bacterium are evident. The bacterial endosymbiont is filled with virion particles. In related images the particles can also be seen loose in the cytoplasm of Trichodina. See the serial section CIL:25687). TEM taken by G. Antipa in 1968 on a Hitachi HU11A operating at 75kV. The negative magnification is 11,500X. The raw film was scanned with an Epson Perfection V750 Pro. This image is best used for quantitative analysis. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 65nm thickness.

中央伊利诺伊州采集的淡水螺类表面栖息的绿色三毛金藻的细胞质。在本视图中，丰富的内共生藻类 zoochlorellae 以及单一的内共生细菌清晰可见。细菌内共生体中充满了病毒颗粒。在相关图像中，颗粒亦可在三毛金藻的细胞质中自由散布。详见序列切片 CIL:25687。1968年由 G. Antipa 在 Hitachi HU11A 电镜（工作电压 75kV）下拍摄的透射电子显微镜图像。负像放大倍数为 11,500 倍。原始胶片使用 Epson Perfection V750 Pro 扫描。该图像适用于定量分析。采用标准戊二醛固定法，随后以四氧化锇处理，酒精脱水，并浸渍于环氧树脂中。微切片厚度约为 65 纳米。
