Von Kossa kit is used for calcium deposits and calcium salt visualisation. Silver ions from silver nitrate replace carbonate and phosphate calcium ions that, under a strong source of light, create a microscopically visible silver glow. Treating the preparation with lithium carbonate prevents false-positive staining. Counterstaining is achieved with Nuclear Fast Red (Kernechtrot) reagent.
Von Kossa kit
Five-reagent kit for simple and reproducible detection of calcium deposits and calcium salt in tissue samples according to Von Kossa. Tissue calcification is associated with metabolic problems in various tissues (like bone marrow and mamma) and in tumours.

P.A.S. Diastase Kit
BioGnost’s P.A.S. Diastase kit is most commonly used for identifying glycogen in liver. Periodic acid enables the molecules containing glycol groups to create aldehydes affected by Schiff’s reagent staining them violet (magenta). Specific stains are created by applying the PAS method on unsubsti-tuted polysaccharides, mucoproteins and glycoproteins, glycolipids and phospholipids. Alpha-amylase enzyme (also known as diastasis) is used for differentiation between glycogen and other PAS-positive structures by dissolving 1→4 glycosidic bonds, causing the glycogen to remain unstained after the PAS reaction. BioGnost’s P.A.S. Diastase kit uses thermostable enzyme which does not require heating to +37°C to be active, but incubat-ing the section at +37°C is preferred in order to achieve better glycogen breakdown. The same tissue section is used as negative control for this reaction, but the sample is not treated using alpha-amylase.
For 100 tests.
