WebThe growth medium controls the pH of the culture and buffers the cells in culture against changes in the pH. Usually, this buffering is achieved by including an organic (e.g., … 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 example, in response to metabolic acid production, or as a consequence of transferring media between … 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 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 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 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 … See more
