WebFeb 10, 2003 · A similar effect on Δψ was observed by the addition of nigericin (Fig. 4E). In both cases, dissipation of the ΔpH resulted in an increase of Δψ. However, in contrast to the effects of benzalkonium or nigericin, adding chloramphenicol or thiamphenicol to MdfA-containing vesicles resulted in a marked dissipation of Δψ (Fig. 4 B and C ...

WebIn the presence of monensin and nigericin, lysosomal pH levels of cells were adjusted to the pH values of the incubation 2-(N-morpholino ethane sulfonic acid buffers: 4.40, 4.90, and … The perceived drawbacks of CO2/HCO3−, namely its volatility and weaker buffering at low pH, have led to the use of exogenous NVBs such as HEPES, PIPES and MES19. It is crucial that the preparation of media containing such buffers carefully considers the CO2/HCO3− equilibrium, which takes place under CO2 … See more Buffers are included in culture media to control acidity, yet the ensuing pH is not routinely monitored. This becomes a quality control issue whenever the components of buffering are being disturbed: for … See more In principle, it is possible to control pH with one of many commercially available buffers, but the most physiologically relevant one is CO2/HCO3−. Incubators maintain a CO2-rich … See more A fundamental reason why changes in medium pH (controlled or unwarranted) can influence cellular physiology is because intracellular pH (pHi) responds to changes in extracellular pH (pHe). This coupling arises … See more In most instances, media are prepared to a neutral or alkaline pH, and over this pH range, the Henderson–Hasselbalch equation (1) is adequate for predicting equilibrium pH. However, the robustness of Eq. 1 depends on … See more myeloma dictionary

Even if efflux somehow has an effect on nigericin susceptibility, loss of function of MerR is expected to reduce the expression of the efflux pump, which would have decreased rather ... Web在含Na+的培养基中，nigericin对ADP诱导的血小板聚集几乎没有影响，轻微抑制凝血酶诱导的血小板聚集。此外，nigericin也降低细胞质pH值。Nigericin对血小板聚集的影响主要是由于其对细胞质pH的影响[1]。K+离子载体nigericin作为Pb2+的离子载体非常有效。 WebOct 5, 1976 · 1.
