Description

Fluorescently labeled, heat- or chemically killed bacteria and yeast in a variety of sizes, shapes, and natural antigenicities

Fluorescent products have been employed to study phagocytosis by fluorescence microscopy, quantitative spectrofluorometry, and flow cytometry.Fluorescein-labeled BioParticles conjugates, which is partially quenched in acidic environments, the fluorescence of the Alexa Fluor, BODIPY™ FL, tetramethylrhodamine and Texas Red™ dye conjugates is uniformly intense over the pH range from 3 to 10.

  • Label (Ex/Em): Alexa Fluor 488 (approx. 495/519nm)
  • Particle: S. aureus (Wood strain, without protein A)
  • Provided as lyophilized powders, approximately 3 x 108 E. coli or S. aureus particles permg solid and approximately 2 x 107 zymosan particles permg solid
  • BioParticles™ conjugates can be reconstituted in buffer of choice for use in phagocytosis assays
  • Fluorescence of BioParticles™ conjugates that are bound to surface of cell (but not internalized) can be quenched by ethidium bromide, trypan blue, or other quenchers
  • Effective as flow cytometry calibration references when sorting bacteria and yeast mutants
