Tartrate Resistant Acid Phosphatase (TRAP) staining Kit
The acid phosphatase (ACP) family is a class of enzymes that are widely found in various tissues, mainly in the lysosomes of cells, so they are often used as markers of lysosomes. Tartrate-resistant acid phosphatase (TRAP) is the most dominant enzyme in the ACP family, found in alveolar macrophages in normal humans and splenocytes in patients with leukemia, and is usually located in the follicles of cells and is not released into the blood. TRAP in the blood is mainly derived from osteoclasts, therefore, by measuring the level of TRAP in the blood, the activity of osteoclasts can be assessed.
The Tartrate Resistant Acid Phosphatase (TRAP) staining kit uses naphthol AS-BI as a substrate, which can be catalyzed by TRAP in an acidic environment to produce phosphoric acid and naphthol. Subsequently, naphthol reacts with diazonium salts to form colored conjugates and is detected. This kit can be used for fresh blood smears, cell smears, and can also be used for the detection of frozen sections and paraffin sections.
