The CARIAD Sperm Vitality Staining Solution utilizes the eosin-nigrosin stain method for swift detection of sperm vitality. Dead sperm cells absorb the eosin, resulting in a red stain due to their altered membrane permeability. In contrast, live sperm with intact cell structures remain unstained. The nigrosin provides a black background, enhancing the distinction between live and dead sperm, making observations more straightforward. This ready-to-use solution offers a simple, one-step staining process.
