Prussian Blue - nuclear fast red staining kit
Cat.No.：E670110 Package：100 Test /500 Test Description Hemoglobin (hemosiderin) is a hemoglobin-derived pigment, golden yellow or brown particles, because of its iron, golden yellow, it is called hemosiderin. When red blood cells are phagocytosed by macrophages, hemoglobin is broken down into iron-free orange blood and iron-containing hemosiderin under the action of lysosomal enzymes. Perls Prussian blue reaction (Prussian blue reaction), also known as hemosiderin staining, that is, after treatment of potassium ferrocyanide and dilute acid can produce blue, common in phagocytes or interstitial, the main display of ferric salt. Perls Prussian blue is a very classical histochemical reaction that is a sensitive, traditional and excellent method of displaying ferric iron in tissues. The staining principle is that potassium ferrocyanide makes the ferric ion from the protein diluted with hydrochloric acid Isolated, ferric iron and potassium ferrocyanide reaction to generate a blue insoluble compound that ferric ferricyanide Prussian blue, so the reaction is called Prussian blue reaction. Ferrous iron ferrocyanide is a very stable compound, after the reaction can be red dye staining, such as nuclear red, eosin, such as neutral red. Prussian blue - nuclear red staining kit commonly used to show that various local hemorrhagic lesions within the organization, common in phagocytes. In determining the hemosiderin deposition, Perls reaction can be confirmed, the staining method can be a good distinction between hemosiderin and other pigments. The dyeing liquid has good stability, can be stored for a long time, is not easy to produce precipitation, has a wide range of applications, can be counterstained. Prussian blue - nuclear red staining kit The counter-staining solution using nuclear red staining solution, is the most classic, the most commonly used complex dye solution. Storage Store at room temperaturefor 12months. Kit Components Component 100 Test 500 Test

Precautions 1. tissue avoid the use of acidic fixatives and chromate treatment can interfere with the preservation of iron.The entire operation of the container should be clean, to avoid the use of metal products。 2. Wash slices and containers using distilled water, because tap water contains iron。 3. Prussian blue working fluid can not be prepared in advance. 4. Prussian blue staining time adjusted according to the sample. 5. For your safety and health, wear lab coats and disposable gloves. 6. This product is only used for scientific research experiment, can not be used for medical and clinical diagnosis. Sangon Biotech
