Buffering system in cell culture media

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.
