Los nuevos conjugados de colorante pHrodo™ verde sensibles al pH y nuestros conjugados de colorante pHrodo™ rojo ofrecen resultados más rápidos y precisos que cualquier otro ensayo de fagocitosis. Los conjugados pHrodo™ verdes no son fluorescentes fuera de la célula a pH neutro, pero tienen un color verde brillante a pH ácido, como los fagosomas. Obtenga una coloración más rápida y resultados más exactos sin la necesidad de pasos de lavado ni colorante supresor.

• Detección específica de fagocitosis y endocitosis
• Variabilidad de señal reducida y temporización mejorada en experimentos sensibles
• Suficiente para hacer 100 pruebas cuando se usan 100 µl en cada pocillo de una placa de 96 pocillos
• Multiplex con otros colorantes compatibles, como la proteína roja fluorescente, TMRM, NucBlue™ Hoechst, y CellROX™ Deep Red

La fluorescencia del nuevo tinte pHrodo™ Green aumenta en gran medida conforme disminuye el pH de neutro a ácido, por lo que es una herramienta ideal para estudiar la fagocitosis y su regulación mediante fármacos y/o factores medioambientales. La falta de fluorescencia fuera de la célula elimina la necesidad del lavado y de la supresión de coloraciones.

Utilice el conjugado pHrodo™ Green E. coli BioParticles™ para la detección de imágenes, la detección de alto contenido, la detección de alto rendimiento y las aplicaciones de flujo. Además, la coloración pHrodo™ Green también está disponible como conjugado de zimosano BioParticles™, S. aureus BioParticles™, o dextrano 10.000 MW. Para crear otros conjugados, como conjugados de anticuerpos, utilice éster pHrodo™ verde STP o maleimida pHrodo™ verde

Preguntas frecuentes

I am performing a phagocytosis assay of macrophages engulfing pHrodo-labeled bacteria. What do you recommend for fixation after the phagocytosis?

pHrodo is relatively non-fluorescent until it enters the acidic phagosome, at which point its fluorescence increases. If you fix the sample, the pHrodo will only reflect the pH of the buffer the cells are in, and not the pH of the phagosome. For this reason, we do not recommend fixing samples. If you want to see how many cells engulfed the labeled bacteria, fix the cells and then place the fixed cells in an acidic buffer for the assay.

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.

How many bioparticles are provided in pHrodo Green E. coli BioParticles Conjugate for Phagocytosis (Cat. No. P35366)?

pHrodo Green E. coli BioParticles Conjugate for Phagocytosis (Cat. No. P35366) contains ~3 x 108 bioparticles/mg bioparticles before conjugation. We do not count the number of bioparticles after conjugation.

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 type of bond that attaches the dyes to the BioParticles probes?

We use amine-reactive dyes to covalently attach fluorescent dyes to all of our BioParticles probes such as the Escherichia coli (K-12 strain) BioParticles probes, Staphylococcus aureus (Wood strain without protein A) BioParticles, and the Zymosan A (S. cerevisiae) BioParticles probes.

Journal:

'Mounting evidence indicates that alcohol-induced neuropathology may result from multicellular responses in which microglia cells play a prominent role. Purinergic receptor signaling plays a key role in regulating microglial function and, more importantly, mediates alcohol-induced effects. Our findings demonstrate that alcohol increases expression of P2X4 receptor (P2X4R), which alters the ... More

Loss or dysfunction of trabecular meshwork (TM) cells has been associated with the development of pathologically elevated IOP, and it is conceivable that replacement of damaged TM cells could restore function to the TM. We propose that the use of TM-like cells derived from induced pluripotent stem cells (iPSCs) created ... More
