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

Electron Microscopy Sciences D-PBS, Formula II Phosphate Buffer Saline 500 ML
All of our Dullbecco's Phosphate Buffer Saline Solutions contain Potassium Chloride, Potassium Phosphate Monobasic, Sodium Chloride, Sodium Phosphate Dibasic, and D-Glucose. Some formulations may contain additional components. Solutions are prepared 1X strength.
Teknova 1M Tris-HCl, pH 8.5. 1000 mL, Sterile.
Tris (tris(hydroxymethyl)aminomethane) is used as a component ofbuffer solutions, especially for solutions ofnucleic acids. The useful buffer range for tris (pH 7–9) is similar to the pH of most living organisms. This, and its low cost, make tris one of the most common buffers in the biology/biochemistry laboratory.

Phosphate Buffered Saline is used as a wash buffer in several lab applications. Without calcium or magnesium, pH 7.4. One 20 liter cubitainer.
Boston Bioproducts Inc PIPES Buffer (0.5 M, pH 6.8) - 100ml
The PIPES Buffer is a zwitterionic buffering agent commonly used in biochemistry and molecular biology for its ability to maintain a stable pH. With a pKa of approximately 6.8, PIPES is effective in the pH range of 6.1 to 7.5, making it suitable for cell culture, enzyme assays, protein purification, and as a running buffer in gel electrophoresis. PIPES is also used in electron microscopy, protein crystallization, and isoelectric focusing and chromatography.
