Sperm Viablity Stain
SA200: Eosin and Nigrosin stain in convienent dropper bottles.
Sperm motility is an important predictor of actual sperm function as it relates to fertility. However, there are some instances when immotile sperm are actually viable. This phenomenon is seen in Kartagener syndrome where there is an ultrastructural defect of the axoneme rendering the sperm immotile but alive. Sperm viability staining measures the integrity of the cell membrane. Viable sperm exclude the stain Eosin-Y thus making the sperm appear white. Dead sperm cannot exclude the stain. Using a dark counterstain such as nigrosin makes the sperm appear dark pink or bright white and are easier to differentiate.
Sperm Viability Stain is used in the AQC™ Sperm Viabilty Quality Control.
