What is the purpose of using Von Kossa's Method in histopathology?

• A. To detect bacterial infections
• B. To stain for Calcium deposits
• C. To visualize cell granules
• D. To embed tissue samples

Answer: (B)

Von Kossa's Method is specifically designed to stain for calcium deposits in tissue sections. This histochemical technique utilizes silver nitrate, which reacts with calcium, resulting in a dark brown or black precipitate where calcium is present. This method is particularly useful in identifying pathological conditions such as metastatic calcifications and mineralized tissues in various diseases, including bone disorders and certain types of tumors. The selective uptake of the silver stain by areas rich in calcium allows for clear visualization under the microscope, aiding in accurate diagnosis and study of tissue specimens.
