支原体染色液 (Dienes染色液) 是一种经典的利用天青美蓝染色检测支原体污染的试剂,经常用于支原体的培养鉴定试验,支原体菌落被染成蓝色,L型细菌菌落在短时间内能染上蓝色,但经15~30min后,由于细菌的新陈代谢作用把美蓝还原成无色,而支原体则长时间保持其染色。该试剂检测细胞含量范围一般为0.1~1×10⁶之间。
操作步骤(仅供参考):
(一)贴壁细胞
1、取洁净盖玻片在70%乙醇中浸泡5分钟或更长时间,无菌超净台内吹干或用无菌于PBS或生理盐水洗涤3次,再用细胞培养液洗涤1次。将盖玻片置于6孔板或其他培养皿内,接种细胞培养过夜,使融合率约为50%~80%。
2、加入Dienes染色液覆盖表面,孵育。
3、弃染色液,PBS或生理盐水洗2次,每次3min,吸尽液体。
4、显微镜下观察。
(二)悬浮细胞
1、低速离心离心后吸去大部分液体保留约液体,再缓缓悬起细胞,滴加至载玻片上,尽量使细胞分布均匀。
2、稍晾干,使细胞贴在载玻片上不易随液体流动。
3、加入Dienes染色液覆盖表面,孵育。
4、弃染色液,PBS或生理盐水洗2次,每次3min,吸尽液体。
5、显微镜下观察。
注意事项:
1、在为了获得细胞沉淀的离心的过程中,对于特殊细胞,如果细胞沉淀不充分,可以适当提高离心力或延长离心时间。
2、为了您的安全和健康,请穿实验服并戴一次性手套操作。
Mycoplasma Stain Solution (Dienes stain) is a classic reagent used for detecting Mycoplasma contamination through staining with Azure B. It is frequently employed in the identification tests of Mycoplasma cultures. Mycoplasma colonies are stained blue. L-type bacterial colonies can be stained blue in a short time, but after 15 to 30 minutes, the bacteria reduce the methylene blue to colorless due to their metabolic activity, whereas Mycoplasma retains its staining for a much longer period. The detection range for cell content using this reagent is generally between 0.1 and 1 × 10⁶.
Operating Steps (For Reference Only):
(I) Adherent Cells
1. Take clean cover slips and soak them in 70% ethanol for 5 minutes or longer. Dry them in a sterile laminar flow hood or wash them 3 times with sterile PBS or physiological saline, followed by one wash with cell culture medium. Place the cover slips in 6-well plates or other culture dishes, inoculate the cells, and incubate overnight until the confluency reaches approximately 50% to 80%.
2. Add Dienes staining solution to cover the surface and incubate.
3. Discard the staining solution and wash twice with PBS or physiological saline, 3 minutes each time, and aspirate the liquid completely.
4. Observe under a microscope.
(II) Suspension Cells
1. Centrifuge at low speed. After centrifugation, aspirate most of the liquid, leaving approximately some liquid. Gently resuspend the cells and add them dropwise onto a slide to ensure uniform cell distribution.
2. Allow to air dry slightly so that the cells adhere to the slide and are not easily washed away by the liquid.
3. Add Dienes staining solution to cover the surface and incubate.
4. Discard the staining solution and wash twice with PBS or physiological saline, 3 minutes each time, and aspirate the liquid completely.
5. Observe under a microscope.
Precautions:
1. During centrifugation to obtain cell pellets, for special cell types, if the cell pellet is insufficient, the centrifugal force can be appropriately increased or the centrifugation time can be extended.
2. For your safety and health, wear a lab coat and disposable gloves during the operation.
