The Molecular Probes™ unlabeled BioParticles™ product line comprises heat- or chemically killed S. aureus (Wood strain, without protein A) and zymosan (S. cerevisiae) cells. These nonfluorescent BioParticles™ products are useful in phagocytosis assays, both as controls and for custom-labeling with reactive dyes.

BioParticles Specifications:
• Label (Ex/Em): Unlabeled
• Particle: S. aureus (Wood strain, without protein A)
• Opsonizing reagent available
