最近看大家常提到支原体污染,就翻了翻书,做了些笔记,现在贴出来和大家分享: 支原体是一种大小介于细菌和病毒之间(最小直径0.2um)并独立生活的微生物.约有1%可通过滤菌器。支原体无细胞壁形态呈高度多形性.可为圆形、丝状或梨形。 支原体形态多变,在光境下不易看清内部结构。电镜下观察支原体膜为三层结构.其中央有电干密度大的密集颗粒群或丝状的中心束。支原体多吸附或散在于细胞表面和细胞之间。横断面与细 ...
This protocol is for use with the D cyclins and employs 488 nm argon laser excitation of propidium iodide and 630 nm NeNe or diode laser excitation of the fluorochrome Cy5 to detect cell cycle-specifi ...

肿瘤细胞在组织培养中占有核心的位置,首先癌细胞是比较容易培养的细胞。当前建立的细胞系中癌细胞系是最多的。另外肿瘤对人类是威胁最大的疾病。肿瘤细胞培养是研究癌变机理、抗癌药检测、癌分子生物学极其重要的手段。肿瘤细胞培养对阐明和解决癌症将起着不可估量的作用。
培养细胞的完全培养基由基础培养基(如MEM)和添加剂(如血清或无血清培养用的某些确定的激素及生长因子)组成,下面介绍培养基及培养基中添加的成分的特性和用途。

细胞株若受到细菌、真菌、支原体、或是特定病毒等之污染时,会严重的影响实验的结果。而细菌、真菌等之微生物污染时,较易自培养基等的外观变化察觉。但是若受到支原体之污染时,细胞之外观较无明显变化,但是其污染会造成细胞之生长速率缓慢、细胞产生病变之型态改变等等变化。 各国细胞库支原体污染的统计表,如下:国家 受支原体污染(%) 报告年度USA-FDA 15 1993(past 30 years)USA- ...
