Summary
Intracellular pH (pHi) regulation is vital for cellular functions. This review covers four key methods for measuring pHi, including microelectrodes and pH-sensitive dyes, highlighting their advantages for single-cell analysis.
Area of Science:
- Cell Biology
- Physiology
Context:
- Intracellular pH (pHi) regulation is crucial for numerous cellular processes and overall organismal health.
- Monitoring pHi is essential for investigating the mechanisms governing its regulation.
Purpose:
- To review and discuss four primary techniques for measuring intracellular pH (pHi).
- To compare the advantages and applications of different pHi measurement methods.
Summary:
- Four major techniques for measuring pHi are presented: distribution of weak acids/bases, pH-sensitive microelectrodes, pH-sensitive dyes, and Nuclear Magnetic Resonance (NMR).
- Microelectrodes offer simultaneous membrane potential monitoring and single-cell application.
- pH-sensitive dyes are a developing technique, noted for ease of use, rapid pHi change monitoring, and applicability to small or single cells.
Impact:
- Provides a comparative overview of pHi measurement techniques, aiding researchers in selecting appropriate methods.
- Highlights the utility of microelectrodes and pH-sensitive dyes for advanced cellular research and single-cell studies.
