肌纤维(Musclefiber)属于肌组织成分,由肌细胞组成,根据形态和功能特点,肌纤维可以分为平滑肌(又称横纹肌)、骨骼肌、心肌。肌纤维染色的方法有很多种,如丽春红法、苯胺蓝法、钨磷钨酸苏木素法等;鞣酸-偶氮荧光桃红法是利用两种酸性染料先后作用而完成鉴别染色。
偶氮荧光桃红染色液其染色原理在于鞣酸容易进入渗透性强的胶原纤维,胶原纤维呈黄色;偶氮荧光桃红容易进入渗透性较低的肌纤维,肌纤维呈红色,偶氮荧光桃红染色液用于区分肌纤维和胶原纤维,对比清晰,不宜褪色,同时可以显示肌上皮细胞,可用于乳腺和皮肤等肌上皮细胞瘤的诊断。该试剂仅适用于科研领域,不适用于临床诊断或其他用途。
操作步骤(仅供参考):
1、常规组织固定于Bouin固定液(Carnoy固定液或中性福尔马林亦可)2~3h。
2、直接转入95%的乙醇中,常规脱水包埋。
3、石蜡切片厚4μm,常规甲苯或脱蜡透明液脱蜡至水,流水冲洗1min。
4、磷钼酸分化液处理10min。
5、入偶氮荧光桃红染色液,浸染10~15min。
6、酸性酒精分化液分化3~5s,无水乙醇反复脱水多次。
7、常规脱水,二甲苯或脱蜡透明液透明,中性树胶封固。
染色结果:
肌纤维和肌上皮细胞:玫瑰红色
胶原纤维:黄色
注意事项:
1、尽量采用Bouin固定液固定组织,其他固定液有可能使染色较淡,也可以10%中性福尔马林替代,但效果不如Bouin固定液。
2、酸性酒精分化液较为重要,应至切片上的红色多余染液脱去,肌纤维呈鲜红色为止。
3、为了您的安全和健康,请穿实验服并戴一次性手套操作。
Muscle fibers are components of muscle tissue and are composed of muscle cells. According to their morphological and functional characteristics, muscle fibers can be classified into smooth muscle, skeletal muscle, and cardiac muscle (note: smooth muscle is not striated muscle; only skeletal and cardiac muscle are striated). There are many staining methods for muscle fibers, such as Ponceau staining, Aniline Blue staining, and Phosphotungstic Acid Hematoxylin staining. The Tannic Acid‑Azophloxine method is a differential staining method using two acidic dyes applied sequentially.
The staining principle of Azophloxine Staining Solution is that tannic acid readily penetrates highly permeable collagen fibers, which stain yellow; azophloxine preferentially enters less permeable muscle fibers, which stain red. Azophloxine Staining Solution is used to distinguish muscle fibers from collagen fibers with clear contrast and good color fastness. It can also demonstrate myoepithelial cells and is used in the diagnosis of myoepithelial tumors of the breast, skin, and other tissues. This reagent is for research use only and not for clinical diagnosis or other purposes.
Protocol (for reference only):
1. Fix tissues routinely in Bouin’s fixative (Carnoy’s fixative or neutral formalin may also be used) for 2–3 hours.
2. Transfer directly into 95% ethanol for routine dehydration and embedding.
3. Prepare 4‑μm paraffin sections, dewax with xylene or dewaxing clearing agent, and hydrate to water; rinse under running water for 1 minute.
4. Treat with Phosphomolybdic Acid Differentiation Solution for 10 minutes.
5. Stain in Azophloxine Staining Solution for 10–15 minutes.
6. Differentiate in Acid Alcohol Differentiation Solution for 3–5 seconds, then dehydrate repeatedly in absolute ethanol several times.
7. Complete routine dehydration, clear with xylene or dewaxing clearing agent, and mount with neutral balsam.
Staining Results:
Muscle fibers and myoepithelial cells: Rose red
Collagen fibers: Yellow
Precautions:
1. Use Bouin’s fixative whenever possible. Other fixatives may result in weaker staining. 10% neutral formalin may be used as an alternative but yields inferior results compared with Bouin’s fixative.
2. Acid Alcohol Differentiation Solution is critical. Differentiate until excess red dye is removed and muscle fibers appear bright red.
3. For your safety and health, wear a lab coat and disposable gloves during operation.
