Elastica-Van Gieson kit is used for staining elastin, connective tissue and collagen. Elastic fibres consist of elastin polymers and elastic microfibrils that make up a 3D network in an extracellular matrix inside connective tissue (skin, elastic cartilage, vascular walls, lung tissue and in vocal cords). Unlike standard histology stains, Weigert Van Gieson reagent (known as a resorcin-fuchsin reagent) displays selective differentiation of tissue samples, even in the early phase of the disease. When using the Elastica-Van Gieson kit, the sections are first treated with Resorcine Fuchsin reagent. The positively charged hydrophobic resorcin-fuchsin dye is present in large amounts and it is deposited owing to electropolarity to acid, negatively charged shells of elastic fibres. After differentiation in diluted alcohol or rinsing in tap water, the nuclei are stained with acid-fast Weigert hematoxylin. The last phase of staining is staining with Fuchsin Acid Van Gieson reagent that contains two dyes (acid fuchsin, picric acid) that simultaneously stain different tissue structures. Acid fuchsin stains collagen fibres intensive red while picric acid stains muscle fibres, erythrocytes and glial fibres yellow. Sections are optimally stained in a short period of time by using a rapid staining method.
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.
TB-Stain Fluorescent Kit
Three-reagent kit for fluorescence-microscopic detection of acid-fast bacteria. Contains TB Auramine-Rhodamine reagent, double amount of TB Decolorizer Fluorescent and TB Permanganate reagent as counterstain.
4 x 100ml bottles.
Alcian Yellow Toluidine Blue kit
Six-reagent kit for staining Helicobacter pylori in gastric tissue sections. This method is one of the most popular non-silver methods for staining of H. pylori, where bacteria are stained blue in contrast to yellow mucins.
Field kit 500ml
Ready to use two-reagent kit for rapid and efficient staining and detection of parasites in haematology samples. Primarily used for staining thin and thick blood smears (dense drop) for purpose of diagnosing blood parasites. Reagents are stored in containers that can be used as staining jars.
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
Giemsa HP kit
Four-reagent kit for staining Helicobacter pylori in gastroscopic sections according to Lennart. Advantages of this method for detecting H. pylori are sensitive and reproducible results and easy performance.
Martius Scarlet Blue (MSB) kit
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.
