Life Science Buffers
Balanced salt solutions and powders used for molecular, protein, nucleic acid, and cell biology applications including cell culture, electrophoresis, ELISA, and chromatography processes; available in a variety of formulations and grades.
Buffer solutions serve to keep pH (acidity or alkalinity) nearly constant in a variety of chemical and biological applications. For example, a bicarbonate buffer helps maintain the pH of blood, a buffered saline maintains cellular contents at a consistent pH level, and buffers help maintain a narrow pH range for enzymes to function correctly.
Most biological samples used in research are kept at a pH of about 7.4. Common biological buffers used for tissue culture include Dulbeccos phosphate buffered saline (PBS), Tris base, HEPES, MOPS, PIPES, and other formulations developed for specific cell lines or applications. Most buffers used in cell culture are also DNase-, RNase-, and protease-free.
The choice of buffer for a particular biological reaction or site depends on several factors:
- Temperature
- Desired or target pH
- Buffer toxicity (to the system)
- Buffer interactions with other system components

Research Products International Corp MOPS [3-(N-morpholino)-propanesulfonic acid], 25 Grams
MOPS, or 3-(N-Morpholino) propanesulfonic acid, is a zwitterionic buffer. MOPS is primarily utilized as a buffering agent to maintain a stable pH in various experimental procedures. It is particularly effective in the pH range of 6.5 to 7.9, making it suitable for applications requiring slightly acidic to neutral pH conditions.
MOPS is commonly used in protein purification, enzyme assays, nucleic acid research, and electrophoresis techniques where a specific pH range needs to be maintained. Its buffering capacity and stability within the desired pH range make it valuable in these applications.
One of the significant advantages of MOPS is its compatibility with biological systems and enzymes. It exhibits minimal interference with enzymatic activity and other biological processes, ensuring reliable and accurate results.
pH Range: 6.5-7.9
