使用用于检测吞噬作用的 pH 敏感性 pHrodo Green E. coli BioParticles 偶联物检测,实现更快的染色,得到更准确的结果,且无需洗涤步骤或淬灭染料。此染料-生物颗粒偶联物相较于其他染料-生物颗粒偶联物可得到更快、更精确的结果,可降低敏感实验中的信号变异性并改善时序。pHrodo Green 染料偶联物在细胞外无荧光,但在吞噬体中呈绿色强荧光,可专门用于检测细胞内吞噬和内吞作用。pHrodo Green E. coli BioParticles 偶联物也可与多种蓝色、红色和远红色染料报告基因(如 Mitosox Red、CellEvent Caspase 3/7 Red、NucBlue、RFP 和 Mitotracker Deep Red 等)配合使用进行多通路检测。

新型 pHrodo Green 染料的荧光随 pH 值从中性到酸性降低而显著增强,使其成为研究吞噬作用以及该作用受药物和/或环境因素调节情况的出色工具。缺乏细胞外荧光,无需清洗步骤和淬灭剂。

在成像、高内涵筛选、高通量筛选和流式应用中使用即用型 pHrodo Green E. coli BioParticles 偶联物。提供的试剂足够在 96 孔板的每个孔中使用 100µL 进行 100 次检测。提供的 pHrodo Green 染料也可作为 Zymosan BioParticles、S. aureus BioParticles 或葡聚糖 10,000 MW 的偶联物。如需制备其他偶联物,例如抗体偶联物,请使用 pHrodo Green STP 酯或 pHrodo Green 马来酰亚胺。

常见问题解答 (FAQ)

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.
