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 PBS 200ml Tablets 500 Tab
PBS, 200ml Tablets refer to pre-weighed tablets used to prepare a specific volume of PBS (Phosphate Buffered Saline) solution.
The buffer tablets are commonly used buffer solution in biological and biochemical research. PBS serves as a versatile buffer for various applications, including cell culture, immunohistochemistry, protein and nucleic acid research, and diagnostic assays. It helps maintain a stable pH and osmolarity, providing optimal conditions for biological reactions and preserving the integrity of cells and biomolecules.
The PBS, 200ml Tablets are designed to simplify the preparation process of PBS solutions. Each tablet contains pre-determined amounts of sodium chloride, sodium phosphate dibasic, and potassium phosphate monobasic. By using these tablets, researchers can save time and ensure accuracy by eliminating the need to weigh and measure individual components.
Apexbio Technology LLC PBS Liposomes(Synonyms: Phosphate Buffered Saline Liposomes, Empty Liposomes, Blank Liposomes), 5mL.
PBS Liposomes consist of phosphate-buffered saline (PBS) encapsulated within lipid bilayers serving primarily as control reagents in macrophage depletion studies involving clodronate liposomes Unlike clodronate-loaded liposomes PBS liposomes lack active agents targeting macrophages and thus do not induce macrophage apoptosis They function to discriminate between the biological effects mediated by liposomal delivery systems versus those specifically attributable to encapsulated clodronate PBS Liposomes are commonly employed in comparative experimental designs to assess specific macrophage depletion outcomes
Teknova DPBS, 500mL, DNase/RNase/Protease/Endotoxin Tested, Sterile. 8 Pack.
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.

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.
