Zenker’s Stock is a fixative solution primarily used in histology and cytology for the preservation of tissue samples. It is commonly used in tissue preparation prior to staining and microscopic examination. Zenker’s Stock is a mixture of mercuric chloride, potassium dichromate, and sodium sulfate, which helps in preserving cellular structure and integrity.

🏭⚗️ Production
Zenker’s Stock is typically prepared by dissolving mercuric chloride (HgCl₂) and potassium dichromate (K₂Cr₂O₇) in distilled water. Sodium sulfate (Na₂SO₄) is added to the solution to stabilize the components. The solution is typically prepared fresh and used for tissue fixation.

🔬 Properties
Zenker’s Stock is a clear, colorless solution. It works as a strong fixative and is known for its ability to preserve cellular structures, including nuclei and cytoplasm, in a relatively preserved state. However, due to the presence of mercury and chromium, it requires proper handling and disposal.

🧪 Applications
Histology: Zenker’s Stock is commonly used to fix tissue samples in histological studies, allowing for the preservation of fine structures for subsequent microscopic examination.
Cytology: It is also used in cytological studies for preserving cellular integrity before staining.
Tissue Staining: After fixation with Zenker’s Stock, tissue samples are typically processed for Hematoxylin and Eosin (H&E) or other specialized stains to examine cellular details under a microscope.
