| Product Introduction | Sperm vitality (the percentage of live sperm) is a key parameter in semen analysis, complementing motility assessment. The eosin-nigrosin staining technique is a vital stain based on membrane integrity: dead sperm with compromised membranes take up the red eosin stain, while live sperm exclude it and appear white against the dark nigrosin background. This kit provides ready-to-use, quality-controlled stains and clear protocols for consistent, reliable results under brightfield microscopy. |
| Product Application | • Routine semen analysis in human and veterinary andrology clinics. • Assessment of sperm cryopreservation success (post-thaw vitality). • Research on male infertility and the effects of toxins, medications, or environmental factors on sperm viability. • Quality control in animal breeding and artificial insemination centers. |
| Product Advantages | • Time-Tested Method: A widely accepted, standardized technique recommended by the WHO for semen analysis. • Clear Differentiation: Produces high-contrast slides where live (unstained) and dead (red-stained) sperm are easily distinguished and counted. • Ready-to-Use Stains: Pre-mixed solutions ensure consistency and save preparation time. • Long Shelf Life: Stains are stable when stored properly, providing reliable performance over time. |
For in vitro diagnostic use.
