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

Phosphate-buffered saline (PBS) is a salt solution that is commonly used in physiological and biochemical experiments. It can be used to maintain pH neutrality or to buffer against changes in pH in order to provide optimal conditions for cellular growth and function. The buffering range is between pH 6.8 and 7.4.
Teknova 1X PBS, 500mL, Sterile.
Phosphate-buffered saline (PBS) is a salt solution that is commonly used in physiological and biochemical experiments. It can be used to maintain pH neutrality or to buffer against changes in pH in order to provide optimal conditions for cellular growth and function. The buffering range is between pH 6.8 and 7.4.
Teknova 0.9% Saline Solution. 1000mL, Sterile. Endotoxin Tested.
Sodium chloride is an essential ingredient in the lab. Not only does it help regulate the pH of solutions, but it also prevents growth of bacteria and other contaminants. In addition, salt is a powerful desiccant, meaning that it can help to dry out wet samples. As a result, salt is often used in a wide variety of laboratory procedures.
Teknova 0.5M Tris, 1.5M Sodium Chloride, 0.5% Tween-20, pH 7.7. 500mL, Sterile.
0.5M Tris,1.5M Sodium Chloride,0.5% Tween-20
Teknova 1X PBS with 0.05% Tween 20, 1% BSA, 1000mL, Sterile.
Phosphate-buffered saline (PBS) is a salt solution that is commonly used in physiological and biochemical experiments. It can be used to maintain pH neutrality or to buffer against changes in pH in order to provide optimal conditions for cellular growth and function. The buffering range is between pH 6.8 and 7.4.
Teknova 1X PBS with 0.1% Tween 80. 1000mL. Sterile.
137.0mM Sodium Chloride, 4.3mM Sodium Phosphate Dibasic, 2.7mM Potassium Chloride, 1.4mM Potassium Phosphate Monobasic,0.1% Tween 80
Teknova 10X ACGU Solution. 100mL, Sterile.
Amino Acids are essential nutrients for cell growth, and thus they are often used in the preparation of growth media. Amino acid solution can help to increase cell viability and growth rate, making it an essential component for cell culture.
