Can I store reconstituted pHrodo BioParticles Conjugates for Phagocytosis and Phagocytosis Kit, for Flow Cytometry?
Yes. Once reconstituted, pHrodo BioParticles Conjugates for Phagocytosis and Phagocytosis Kit, for Flow Cytometry (Cat. Nos. P35367, P35361, P35360, P35366, P35364, P35365, A10010) can be stored at 2 - 8 degrees C for several weeks, as long as sodium azide is added to a final concentration of 2 mM. If no sodium azide is added, the cell suspension needs to be used right away or on the same day to avoid contamination. DO NOT FREEZE the resuspended pHrodo bioparticle conjugates.

Are the Invitrogen BioParticles products sterile?
While the bacteria have been attenuated with formaldehyde and alcohol desiccation, the BioParticles products are not considered sterile, and we do not recommend incubation of more than 4 hours. This applies to all of our dye-labeled (pHrodo, Alexa Fluor, etc.) and unlabeled BioParticles products.
What is the concentration of bacterial particles for pHrodo BioParticles Conjugates for Phagocytosis?
The bacterial particles per weight for pHrodo BioParticles Conjugates for Phagocytosis, is as follows:
pHrodo E. Coli BioParticles Conjugate for Phagocytosis (Cat. Nos. P35360, P35361, A10025) contains 3 x 108 particles/mg.
pHrodo S. aureus BioParticles Conjugate for Phagocytosis (Cat. Nos. A10010, P35367) contains 3 x 108 particles/mg.
pHrodo Zymosan BioParticles Conjugate for Phagocytosis (Cat. No. P35365) contains 2 x 107 particles/mg.

Can I use pHrodo Deep Red E. Coli Bioparticles Conjugate for Phagocytosis (Cat. No. P35360) with cell types other than RAW or MMM (J774A.1) cells?
Yes. You can use cell types for pHrodo Deep Red E. Coli Bioparticles Conjugate for Phagocytosis (Cat. No. 35360) other than RAW or MMM (J774A.1). The final concentration of BioParticles per cell and incubation time would have to be optimized if using other cell types. You may follow the protocol for the RAW and MMM cells and determine if any changes are required for your cells of interest.
