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
Crescent Chemical Co Inc TRIS BUFFER PH 8.0 1 M SOLN
Tris buffer pH 8.0, 1 M solution molecular biology grade DNase, RNase, Protease not detected. The pH value of Tris buffer is temperature and concentration dependent. For Tris buffers, pH increases about 0.03 unit per degree C decrease in temperature, and decreases 0.03 - 0.05 uni

Bis-Tris, also known as bis-Tris methane, is a zwitterionic buffering agent used in biochemistry and molecular biology. It is a bis(2-hydroxyethyl)amine and Tris family buffer that is useful for a pH range of 5.8 – 7.2. Bis Tris is a common component of many buffer systems for various types of electrophoresis. Bis-Tris may form a complex with some common metals, such as Cu(II) and Pb(II), and formation constants should be taken into account when using this buffer in a solution containing metal ions. Bis-Tris can be used as a substitute for the highly toxic buffer cacodylate.
