MOBS (CAS 115724-21-5)

MOBS, or 4-Morpholineethanesulfonic acid, is a zwitterionic biological buffer used extensively in biochemistry and molecular biology research for its capability to stabilize pH within the range of 6.5 to 7.9. As a morpholino buffer, MOBS is particularly valued for its low UV absorbance and minimal reactivity with biological molecules, making it ideal for applications where interference with the sample must be minimized, such as in UV spectroscopy and other sensitive analytical techniques. The buffering action of MOBS arises from its ability to accept or donate protons in response to changes in the hydrogen ion concentration, effectively maintaining a stable pH environment crucial for many enzymatic reactions and protein interactions. This property is especially important in maintaining the integrity and activity of biomolecules during experiments. In research, MOBS has been utilized in the preparation of buffers for electrophoresis, especially in the separation of proteins and nucleic acids where precise pH control is necessary to avoid denaturation and to ensure consistent migration patterns. Additionally, its good solubility and low ionic strength make it suitable for use in cell culture environments, where it helps in maintaining physiological pH without precipitating essential ions, thus supporting cell health and proliferation in in vitro experiments.
