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 Phosphate Buffered Saline, 10X Solution, 500 Milliliters
PBS 10X Solution is a concentrated phosphate-buffered saline widely used in cell biology, immunohistochemistry, and molecular biology. It contains phosphate ions that maintain physiological pH and ionic strength, creating a stable environment for cells, tissues, and biomolecules. The 10X concentration allows for easy dilution to 1X for various applications such as washing, resuspending, or preparing samples. The phosphate buffer system resists pH changes, ensuring experimental consistency. PBS 10X is a reliable, versatile reagent that supports reproducible results in biological and biochemical workflows.

Sigma Aldrich Fine Chemicals Biosciences TrizmaR hydrochloride solu
A series of Pre-mixed SOLUTIONons of TRIZMA Base and TRIZMA HCl to provide commonly used pH values for Tris buffers. No mixing or pH adjustment necessary. Guaranteed accuracy /- 0.1 pH units.
Teknova 200mM Tris, pH 7.0. 1mL, Sterile. 50 Pack
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.
