Vitality Stain (Dead – Live) Sterile
Product Overview
The Spermatozoa Morphology and Vitality Stain is a dual-purpose diagnostic reagent formulated for the microscopic evaluation of sperm structure and viability. Sterile and ready-to-use, this stain allows for simultaneous assessment of sperm morphology and vitality, distinguishing between live (viable) and dead (non-viable) spermatozoa with high clarity and accuracy.
Typically incorporating a combination of eosin Y and nigrosin, this stain uses a vital dye exclusion principle:
- Live spermatozoa with intact membranes exclude the stain and remain unstained (clear or light gray)
- Dead spermatozoa with compromised membranes absorb the dye and appear pink or red against a dark background
This method is essential for evaluating fertility potential, sample quality, and the effects of storage or treatment in human and veterinary reproductive medicine.
Key Features:
- Provides simultaneous assessment of sperm vitality and morphology
- Differentiates live (unstained) vs. dead (stained) spermatozoa
- Highlights head, midpiece, and tail abnormalities for morphological grading
- Sterile formulation ensures contamination-free results
- Suitable for use in fertility clinics, andrology labs, and veterinary practice
- Compatible with manual microscopy and routine semen analysis protocols
The Spermatozoa Morphology Vitality Stain is an essential tool for reproductive diagnostics, enabling clear, reliable evaluation of sperm health, viability, and structural integrity in both clinical and research environments.
