Congo Red Puchtler kit is used for staining amyloids (amorphous clusters) in histology sections. Despite their variable protein composition, amyloid deposits are linked by fibril beta-sheets formation. Congo Red dye binds to fibrils and form a regular pattern of dye molecules during the process. The structural regularity of the dye under polarised light demonstrates double refraction of light by displaying green colouration. High pH level and ionic strength of solutions according to Puchtler achieve higher dye specificity to amyloid.
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.
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.
Three-reagent Hematoxylin-Basic Fuchsin-Picric acid staining kit for detection of cardiac muscle changes after ischemia or myocardial infarction. H.B.F.P. kit is a non-enzymatic histochemical technique for detection of early myocardial ischemia with vivid contrast.
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.
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.
