软骨组织由软骨细胞和软骨基质组成,软骨组织及其周围的软骨膜构成软骨,软骨染色的方法有很多种,如甲苯胺蓝法、阿利新蓝法、番红O法等。软骨根据基质内所含纤维素成分不同可分为透明软骨、弹性软骨、纤维软骨。透明软骨主要分布于上呼吸管道、肋骨内侧端、短骨关节面等处。
Unna碱性美蓝又称多色亚甲蓝 (Polychrome Methylene Blue),是亚甲基蓝的氧化混合物,通过特定工艺制备后呈现蓝、紫、红等多色性,在微生物学、病理学及材料科学中有独特应用。透明软骨染色液 (Unna碱性美蓝法)采用茜素红和碱性美蓝结合染色,骨质(钙盐沉着处)和茜素红结合形成红色,软骨与多色亚甲蓝反应呈紫色,细胞质呈黄色,胞核蓝色,此法为6-8个月胎儿指骨最佳染色法。由碳酸钾、美蓝、茜素红等组成。该试剂仅用于科研领域,不适用于临床诊断或其他用途。

自备材料:
1、系列乙醇、蒸馏水、二甲苯或环保脱蜡液、环保透明液、中性树胶
2、显微镜
操作步骤(仅供参考):
1、组织用90%乙醇固定12~24小时,石蜡包埋切片。切片厚度3~5μm,脱蜡至水,蒸馏水洗。
2、入茜素红S染色液染色5~20min,蒸馏水稍洗。
3、入Unna碱性美蓝染色液复染2~6min,95%乙醇分色至染色清晰。
4、常规脱水,二甲苯或环保透明液,中性树胶封固。
染色结果:
钙盐沉着处呈红色,软骨基质呈紫色,细胞质呈黄色,细胞核蓝色。
注意事项:
1、在不溶性钙染色中茜素红S的染色时间要根据钙盐的含量来确定,应在显微镜下观察,直到着色反应强烈而不弥散为止。
2、经过茜素红S染色液染色后,钙沉积物是双折射的。
3、Unna碱性美蓝染色液易挥发,染色时应加盖。
4、为了您的安全和健康,请穿实验服并戴一次性手套操作。
Cartilage tissue is composed of chondrocytes and cartilage matrix. Cartilage tissue and the surrounding perichondrium constitute cartilage. There are many staining methods for cartilage, such as toluidine blue method, alcian blue method, safranin O method, etc. According to the different fibrous components in the matrix, cartilage can be divided into hyaline cartilage, elastic cartilage and fibrocartilage. Hyaline cartilage is mainly distributed in the upper respiratory tract, medial end of the ribs, articular surfaces of short bones and other sites.
Unna alkaline methylene blue, also known as polychrome methylene blue, is an oxidized mixture of methylene blue. It exhibits polychromatism including blue, purple and red after preparation by a specific process, and has unique applications in microbiology, pathology and materials science. Hyaline Cartilage Staining Solution (Unna alkaline methylene blue method) uses alizarin red combined with alkaline methylene blue for staining. Bone tissue (where calcium salts are deposited) binds to alizarin red and appears red; cartilage reacts with polychrome methylene blue and appears purple; cytoplasm is yellow and nuclei are blue. This method is the optimal staining method for fetal phalanges at 6–8 months of gestation. It is composed of potassium carbonate, methylene blue, alizarin red, etc. This reagent is for research use only and not suitable for clinical diagnosis or other purposes.
Product Components and Storage Conditions:
| T1511541 | Component | 2×50mL | Storage |

Materials Required (User-supplied):
1. Graded ethanol, distilled water, xylene or environment-friendly dewaxing solution, environment-friendly clearing solution, neutral balsam
2. Microscope
Protocol (For Reference Only):
1. Fix tissues in 90% ethanol for 12–24 hours, embed in paraffin and section. Section thickness: 3–5 μm. Dewax to water, then rinse with distilled water.
2. Stain in Alizarin Red S Staining Solution for 5–20 minutes, rinse briefly with distilled water.
3. Counterstain in Unna Alkaline Methylene Blue Staining Solution for 2–6 minutes, differentiate in 95% ethanol until staining is clear.
4. Perform routine dehydration, clear in xylene or environment-friendly clearing solution, and mount with neutral balsam.
Staining Results:
Areas of calcium deposition: red
Cartilage matrix: purple
Cytoplasm: yellow
Cell nuclei: blue
Precautions:
1. For staining insoluble calcium, the staining time of Alizarin Red S should be determined according to calcium content, and observed under a microscope until the staining is intense and non-diffuse.
2. After staining with Alizarin Red S Staining Solution, calcium deposits are birefringent.
3. Unna Alkaline Methylene Blue Staining Solution is volatile; cover the container during staining.
4. For your safety and health, please wear a lab coat and disposable gloves during operation.
