CIL:39757, Mus musculus, cardiac muscle cell. In Cell Image Library
收藏资源简介:
Primary fixation included: 2.5 % glutaraldehyde, 2% formaldehyde in 0.1 M Na-phosphate buffer, pH 7.4. Post-fixed in 2% OSO4 in 0.1 M Na-phosphate buffer, pH 7.4. Stained en bloc in 1% uranyl acetate. The tissue was then dehydrated in a graded series of ethanol and infiltrated with Spurr's resin. Thin sections of 70 nm were trimmed using a diamond knife and post-stained in uranyl acetate and lead citrate. This micrograph image was taken using a Phillips CM 100 transmission electron microscope at an accelerating voltage of 80kV.
前固定液配方为:溶于0.1M磷酸钠缓冲液(pH 7.4)中的2.5%戊二醛(glutaraldehyde)与2%甲醛(formaldehyde)。随后使用溶于0.1M磷酸钠缓冲液(pH 7.4)的2%四氧化锇(OSO4)进行后固定。采用1%醋酸铀酰(uranyl acetate)进行块染。将组织经梯度乙醇系列脱水后,以Spurr树脂(Spurr's resin)进行渗透浸润。使用金刚石刀(diamond knife)修块,切取70nm超薄切片,再以醋酸铀酰与柠檬酸铅(lead citrate)进行复染。本显微图像采用飞利浦CM 100透射电子显微镜(transmission electron microscope)拍摄,加速电压为80kV。
