本产品为组织病理专用染色试剂,主要用于石蜡切片、冰冻切片中淀粉样物质(如AL型、AA型淀粉样变)的特异性染色,可通过光镜观察淀粉样物质的分布与形态,偏振光下可呈现特征性苹果绿双折光,用于病理诊断及相关实验研究。
使用方法(仅供参考以石蜡切片为例):
1、脱蜡至水:将石蜡切片依次放入二甲苯Ⅰ(5分钟)→ 二甲苯Ⅱ(5分钟)→ 100%乙醇(2分钟)→ 95%乙醇(2分钟)→ 80%乙醇(2分钟),最后用蒸馏水漂洗2次,每次1分钟。
2、染色处理:将切片放入0.5%甲醇刚果红染液中,室温下染色10-20分钟,染色期间可轻轻晃动染液,确保切片染色均匀。
3、分化处理:取出切片,放入碱性乙醇分化液(0.2%KOH溶于80%乙醇)中快速分化5-10秒,期间需在显微镜下观察,直至背景近无色、淀粉样区域保留红色,立即取出。
4、水洗返蓝:将切片用流水冲洗3-5分钟,彻底去除残留的分化液,避免影响后续染色效果。
5、复染细胞核:将切片放入Mayer苏木素染液中复染1-2分钟,取出后用流水冲洗,直至细胞核呈蓝色。
6、脱水透明:依次放入梯度乙醇(95%乙醇2分钟→100%乙醇2分钟×2次)→ 二甲苯(5分钟×2次),使切片透明。
7、封固观察:用中性树胶滴加在切片上,盖上盖玻片封固,待树胶干燥后,光镜或偏振光显微镜下观察。
染色结果:
光镜下:淀粉样物质呈橘红色,细胞核呈蓝色,背景无色或淡粉色。
偏振光显微镜下:淀粉样物质呈特征性苹果绿双折光,为阳性结果。
注意事项:
1、为了您的安全和健康,请穿实验服并戴一次性手套操作。

This product is a special staining reagent for histopathology, mainly used for the specific staining of amyloid substances (such as AL-type and AA-type amyloidosis) in paraffin sections and frozen sections. The distribution and morphology of amyloid substances can be observed under light microscopy, and they exhibit characteristic apple-green birefringence under polarized light, which is used for pathological diagnosis and related experimental research.
Usage (for reference only, taking paraffin sections as an example):
1. Deparaffinization to water: Place the paraffin sections sequentially in Xylene I (5 min) → Xylene II (5 min) → 100% ethanol (2 min) → 95% ethanol (2 min) → 80% ethanol (2 min), and finally rinse with distilled water twice, 1 min each time.
2. Staining: Immerse the sections in 0.5% methanol Congo Red staining solution and stain at room temperature for 10–20 min. Gently agitate the staining solution during the process to ensure uniform staining.
3. Differentiation: Take out the sections and differentiate rapidly in alkaline ethanol differentiation solution (0.2% KOH dissolved in 80% ethanol) for 5–10 seconds. Monitor under a microscope until the background is nearly colorless and the amyloid regions retain red color, then remove immediately.
4. Washing and bluing: Rinse the sections under running water for 3–5 min to completely remove residual differentiation solution and avoid affecting subsequent staining results.
5. Nuclear counterstaining: Counterstain the sections in Mayer's hematoxylin solution for 1–2 min, then rinse under running water until the cell nuclei appear blue.
6. Dehydration and clearing: Place sequentially in graded ethanol (95% ethanol 2 min → 100% ethanol 2 min, twice) → Xylene (5 min, twice) to clear the sections.
7. Mounting and observation: Add neutral balsam onto the sections, cover with a coverslip, and after the balsam dries, observe under light microscopy or polarized light microscopy.
Staining Results:
Light microscopy: Amyloid substances appear orange-red, cell nuclei appear blue, and the background is colorless or pale pink.
Polarized light microscopy: Amyloid substances exhibit characteristic apple-green birefringence, indicating a positive result.
Precautions:
1. For your safety and health, please wear a laboratory coat and disposable gloves during operation.
2. This product is for research use only; strictly prohibited for other purposes.
