Alcian Blue – P.A.S. kit
Seven-reagent Alcian Blue – Periodic Acid-Schiff kit for staining acid mucopolysaccharides according to Mowry. Enables differentiation between acid mucins (stained light blue) and neutral mucins, glycogens and glycoproteins (stained red, magenta).
Alcian Blue pH 2.5 kit
Three-reagent kit for staining acid mucopolysaccharides according to Dorling and sulphated and carboxylated sialomucins blue. Slides are counterstained with Nuclear Fast Red (Kernechtrot) reagent to fully detect the presence of Alcian Blue positive staining.
Colloidal Iron kit
Six-reagent kit used for visualisation of carboxylated and sulphated groups of acid mucopolysaccharides and proteoglycans. This method can be combined with the PAS method; that way glycogen and neutral mucopolysaccharides would get differentially stained characteristically magenta.
Congo Red Highman kit
Three-reagent kit for staining amyloids, characteristic for use of alkaline solution as differentiation medium in order to avoid undesirable non-specific colouration of cellular substances. Amyloid deposits display green colouration under polarised light.
Congo Red Puchtler kit
Three-reagent kit for staining amyloids, characteristic by its high ionic strength and pH enhancing the specificity of Congo Red dye binding to amyloid clusters. This method developed by Puchtler remains the gold standard for amyloids in tissue sections. Amyloid clusters have the property of double refraction that enables green colouration under polarised light.
Eosin and Nigrosin Vital kit
Two-reagent kit containing separate dyes for rapid detection of sperm vitality and simple visualisation of dead and living sperm cells. The Nigrosin stain provides dark background for easier recognition of both viable and non-viable spermatozoa.
Five-reagent DNA staining kit according to Feulgen. For use in semiquantitative DNA determination in histological and cytological samples. The specimen is first treated with hydrochloric acid creating an aldehyde group of DNA that can be visualised by Schiff (BioSchiff) reagent. This reaction is specific for nuclear DNA.
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.
Fouchet-Van Gieson kit
Three-reagent kit for visualisation of bilirubin and collagen according to Kutllick. Bilirubin is a yellow-brown pigment, but changes to green due to oxidation induced by Fouchet reaction. Green bilirubin can easily be detected on yellowish and pink coloured background.
