Sperm Vitality Staining Solution (Eosin-Nigrosin Staining)
Rapid Membrane Integrity Assessment: One-Step Eosin-Nigrosin Vitality Stain
Differentiating Live from Dead:
Performance Features:
High-Contrast Visualization: Nigrosin creates a dark, uniform background, making live (unstained) sperm stand out with brilliant clarity.
One-Step Efficiency: Our optimized formula combines staining and background contrast into a single step, significantly faster than traditional two-step protocols.
ICSI Selection: Provides essential data for selecting viable sperm in zero-motility cases. The WHO Laboratory Manual (6th Edition) recommends vitality testing when motility is below 40%.
