Bovine sperm. LIVE/DEAD® Sperm Viability Kit.

A mixture of live and dead bovine sperm cells stained with the dyes provided in our LIVE/DEAD® Sperm Viability Kit (Cat. no. L7011). Live sperm with intact membranes are labeled with our proprietary cell-permeant nucleic acid stain, SYBR® 14, and fluoresce green. Dead sperm, which have been killed by unprotected freeze-thawing, are labeled with propidium iodide (Cat. no. P1304MP, P3566, P21493) and fluoresce red-orange. The image was contributed by Duane L. Garner, School of Veterinary Medicine, University of Nevada, Reno, and Lawrence A. Johnson, USDA Agricultural Research Service.
