含铁血黄素 (Hemosiderin)是一种血红蛋白源性色素,为金黄色或棕黄色颗粒,因其含铁,且为金黄色,故称为含铁血黄素。当红细胞被巨噬细胞吞噬后,在溶酶体酶的作用下,血红蛋白被分解为不含铁的橙色血质和含铁的含铁血黄素。Perls普鲁士蓝反应 (Prussian blue reaction)又称为含铁血黄素染色,即经过亚铁氰化钾和稀酸处理后可以产生蓝色,常见于吞噬细胞或间质内,主要显示三价铁盐。在极少数情况下,铁存在于其还原态的亚铁之中,Lillie法是显示二价铁的很好的方法,其特异性较好。

临用前,取A、B等量混合即为Lillie Stain,不宜提前配制。
使用方法
1、组织固定于10%中性福尔马林或其他碱性固定液,常规脱水包埋。
2、切片厚度4μm,常规脱蜡至水。
3、蒸馏水水洗1min。
4、切片入Lillie stain (见注意事项4),浸染 25-30min。
5、蒸馏水充分冲洗2-5min。
6、入核固红染色液,淡染细胞核5-10min。
7、蒸馏水冲洗1-5s。
8、常规脱水透明,中性树胶封固。
染色结果
二价铁: 深藤氏蓝
细胞核、其他组织: 红色
注意事项
1、该染色法适用于石蜡切片、冰冻切片和树脂切片,切片脱蜡应尽量干净。
2、组织固定常采用10%中性福尔马林,经普通福尔马林长期固定后。
3、整个操作过程中容器要干净,避免用金属铁制品。
4、所有切片都应使用同一个阳性对照切片,选择适合的对照非常重要。
5、系列乙醇应经常更换新液。
6、冰冻切片和细胞的染色,最好根据具体情况摸索实验条件。
7、为了您的安全和健康,请穿实验服并戴一次性手套操作。
Hemosiderin is a hemoglobin-derived pigment that exists as golden yellow or brownish yellow granules. It is named hemosiderin due to its iron content and golden yellow color. When red blood cells are phagocytosed by macrophages, hemoglobin is decomposed into iron-free hematoidin and iron-containing hemosiderin under the action of lysosomal enzymes. The Perls Prussian blue reaction, also known as hemosiderin staining, produces a blue color after treatment with potassium ferrocyanide and dilute acid. It is commonly found in phagocytes or interstitium and mainly demonstrates ferric iron salts. In rare cases, iron exists in its reduced ferrous form. The Lillie method is an excellent and highly specific technique for detecting ferrous iron.

Before use, mix equal volumes of Solution A and Solution B to prepare Lillie Stain. Do not prepare the stain in advance.
Operating Procedure
1. Fix tissues in 10% neutral buffered formalin or other alkaline fixatives, followed by routine dehydration and embedding.
2. Cut sections at a thickness of 4 μm, then perform routine dewaxing to water.
3. Rinse with distilled water for 1 min.
4. Immerse sections in Lillie Stain (refer to Note 4) for 25-30 min.
5. Rinse thoroughly with distilled water for 2-5 min.
6. Transfer sections to Nuclear Fast Red Staining Solution and stain nuclei lightly for 5-10 min.
7. Rinse with distilled water for 1-5 s.
8. Dehydrate and clear sections using standard protocols, then mount with neutral balsam.
Staining Results
Ferrous iron: Deep Turnbull’s blue
Cell nuclei and other tissues: Red
Precautions
1. This staining method is suitable for paraffin sections, frozen sections, and resin sections. Ensure thorough dewaxing of sections.
2. Tissues are typically fixed in 10% neutral buffered formalin. Avoid prolonged fixation in plain formalin.
3. Use clean containers throughout the procedure and avoid contact with ferrous metal products.
4. Include a single positive control section for all test sections. Selecting an appropriate control is critical for valid results.
5. Replace serial ethanol solutions regularly with fresh ones.
6. For staining frozen sections and cells, optimize experimental conditions according to specific sample types.
7. For your safety and health, wear a lab coat and disposable gloves during operation.
