Nidacon Sperm VitalStain

Optimised one step staining technique for assessment of sperm vitality.

One of the basic tools used in semen analysis, sperm vitality assessment is a key component of successful IVF. Sperm VitalStain, which contains both eosin and nigrosine, is a key component of Nidacon’s optimised sperm vitality assessment staining technique. Our technique is based on the principle that dead cells (i.e., those with a damaged plasma membrane) will absorb the eosin and exhibit a red stain. Th nigrosine is used as a counterstain to facilitate visualization of the unstained (white) live cells.
