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

S2 Media 1L 1x Phosphate Buffered Saline (PBS), pH 6.0, 1L Media Bottle, 1ea
S2Media™ 1x Phosphate Buffered Saline (PBS), pH 6.0 has many applications due to its isotonic nature, including uses as a rinse fluid, diluent, and buffer. Phosphate salts are nontoxic to living cells and have a high buffering capacity. pH maintenance is important in retaining cell viability and in the recovery and revitalization of injured or damaged cells during bacterial culture and analysis. PBS is generally used as a 10mM working solution containing a mixture of sodium chloride and inorganic phosphate salts.• Product meets AOAC, APHA, BAM, CLSI, SM-Dairy, SMWW, and USP-NF reference methods and performance criteria.• For in vitro diagnostic (IVD) use.• PBS should be used by trained professionals within a laboratory setting. • Product is not intended for use in the diagnosis or treatment of disease or other human conditions.
Teknova 10X PBS-MK, 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.

Alkali Scientific PIPES Sodium Salt [Piperazine N,N' bis(2 ethanesulfonic acid) sodium salt], 250 Grams
PIPES Sodium Salt (Piperazine N,N' bis(2 ethanesulfonic acid) sodium salt) is a high-purity biochemical reagent provided in a 250G pack. It is widely used as a buffering agent in biological and biochemical assays due to its excellent stability in a wide pH range. The sodium salt form of PIPES is ideal for maintaining stable pH conditions in sensitive biological environments. It is commonly used in molecular biology, protein analysis, and enzyme assays, as it does not interfere with biological systems. PIPES Sodium Salt is also used in chromatographic applications and as a mobile phase additive in high-performance liquid chromatography (HPLC).
