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: Zymosan (S. cerevisiae)
• Opsonizing reagent available
