Product Introduction:

In the staining technique, in most cases, bile pigment refers to the assembly of all types of bile pigments in the same reaction mode, including conjugated bilirubin, unconjugated bilirubin, biliverdin, bilirubin like, etc. These substances have different chemical structures and different physical properties, especially their solubility in water and ethanol. Most liver tissue sections are a mixture of biliverdin, conjugated bilirubin, and unconjugated bilirubin under the microscope. It is more common in bile duct obstruction, abnormal bilirubin metabolism, hepatocyte necrosis or degeneration. It is important to distinguish between bile pigment and lipofuscin in liver histological examination. Both of them are yellowish brown in ordinary HE staining, which is not easy to distinguish.

Hepatobiliary pigment staining kit adopts modified Fouchet method, which makes biliverrin appear green by the oxidation of iron, and the melanin appears black after the fiber is stained. This method is a commonly used special staining method for bile pigment, and its effect is better than other staining methods.
