BioGnost’s Sudan Black B Lipid kit is used for specific lipids staining in cytochemistry. Sudan Black B is a mildly alkaline dye that interacts with an acid group of lipids. Sudan Black stains a variety of lipids, including neutral fats, phospholipids, and sterols.
Sudan Black B Lipid kit
Four-reagent kit for specific lipid staining in cytochemistry. Sudan Black dye stains a few types of lipids, including neutral fats, phospholipids and sterols. It contains a double amount of Sudan Black B, solution.
Martius Scarlet Blue (MSB) kit, 6x100ml+1x250ml
Seven-reagent kit used for fibrin visualisation, especially of older clusters. This method is a modification of Masson Trichrome and is ideal for studying connective tissue and vascular pathology.
Grocott kit, stabilised
Seven-reagent kit for visualization of fungi and histological argentaffin structures in general (such as basal membranes). Green counterstain provides clear and visually rich contrast to target structures stained black.
TB-Stain Histo kit
Three-reagent kit for staining acid-fast bacteria (pathogenic mycobacteria) in histology sections, sputum, smears and culture smears according to Ziehl-Neelsen. Heating of the carbol-fuchsin solution is avoided in this protocol hence omitting the release of hazardous phenolic vapours.
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.
BioGram 4 kit
Four-reagent kit for identification of bacteria according to Gram. Kit contains Gram Crystal Violet 1% solution, stabilized Gram Lugol solution, double amount of Gram Decolorizer solution 2 and Gram Safranin solution as counterstain.
5×100 ml bottles
Elastica-Van Gieson kit
Four-reagent kit for staining elastic fibres and differentiation between elastic tissue, collagen and other types of connective tissue. The rapid method enables a satisfactory result with shorter section staining time.
BioGram ECO kit
Four-reagent phenol-free kit for the identification of bacteria according to Gram. Kit contains Gram Crystal violet, phenol free reagent, Gram Sodium hydrogencarbon, solution, stabilized Gram Lugol solution, double amount of Gram Decolorizer solution 2 and Gram Safranin solution as counterstain.
2×50 mL+4×100 mL bottles
