BioGnost’s Eosin and nigrosine vital kit is used for the detection of sperm vitality. Using the kit is extremely fast and simple. During sample staining eosin Y dye enters dead sperm cells (cells with damaged plasma membrane) and stains them red. Nigrosine dye provides dark contrast for better visualisation of living, non-stained sperm cells.
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.

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.
