Stains Reagents And Dyes
Stain Kits
Nuclear Fast Red (Kernechtrot) Reagent
Nuclear Fast Red dye solution for staining nuclei. Counterstain in many special staining kits.
Stain Kits
Oil Red O Kit
Four-reagent kit for selective staining and detection of fat cells and neutral fats according to Johnson. It can be used with frozen sections and fresh smears to detect obesity-linked pathologies such as dyslipidemia and diabetes type.
Stain Kits
Orcein kit
Five-reagent kit for visualisation of hepatitis B surface antigen (HBsAg) seen as viral inclusion bodies in hepatocytes, for elastic fibres and copper associated protein in tissue sections. It can be used with frozen sections.
Stain Kits
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.
Stain Kits
P.A.S. kit
Five-reagent Periodic Acid-Schiff kit for staining aldehydes, muccopolysaccharides, mucoproteins and lymphocytes according to Hotchkiss-McManus. P.A.S. staining may also be used for the demonstration of fungal organisms in tissue sections.
Stain Kits
P.A.S.M. / Jones kit, stabilised
Seven-reagent Periodic Acid Silver Methenamine kit for staining kidney glomerular basement membranes. Kit includes red counterstain which provides visually rich contrast to target structures stained black.
Papanicolaou Rapid Staining Kit, for 100 Tests
Ready-to-use eight-reagent kit (in 18 containers that can be used as staining jars) for rapid progressive gynecology and non-gynecology cytological samples. Contains xylene substitute as clearing agent and xylene substitute-based medium for permanent covering of samples.
PAP-100T for 100 tests
