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.
