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
Bioworld TAE Buffer, Quick-Mix Pack (10X), 4 PK(s)
Product DescriptionTAE (Tris-Acetate-EDTA) buffer quick-mix pack prepares 1 L of 10X concentration. This solution has a pH level between 8.2 – 8.4 and is stored at room temperature.TAE is used for electrophoresis of nucleic acids in agarose and polyacrylamide gels. It can be used for both genomic and large supercoiled DNA, and can also be used as both a running buffer and a gel preparation buffer. It is recommended for resolution of RNA and DNA fragments larger than 1500 bp, for genomic DNA and for large supercoiled DNA. TAE buffer has a relatively low buffering capacity and therefore replacement of the buffer during prolonged electrophoresis is recommended.

National Diagnostics Tris-Glycine Electroblotting Buffer (10X) 4 Liter
Tris-Glycine Electroblotting Buffer (10X) is a concentrated solution in distilled/deionized water. This buffer is intended to act as the tank buffer in Western electroblotting procedures. It is also the recommended buffer for use with nitrocellulose and nylon membranes.Tris-Glycine Electroblotting Buffer (10X) is already in solution which eliminates the weighing, mixing and adjusting of the pH necessary with powdered buffers. To prepare 1 liter of working strength buffer, add 100 ml of Tris-Glycine Electroblotting Buffer to 200 ml of methanol and 700 ml of distilled/deionized water.Tris-Glycine Electroblotting Buffer (10X) contains 0.25M Tris base and 1.92M glycine, with a pH of 8.4.
Sigma Aldrich Fine Chemicals Biosciences HEPES BioUltra for molecul10G
HEPES has been described as one of the best all-purpose buffers available for biological research. At biological pH the molecule is zwitterionic and is effective as a buffer at pH 6.8 to 8.2. HEPES has been used in a wide variety of applications including tissue culture. It is commonly used to buffer cell culture media in air. HEPES finds its usage in in vitro experiments on Mg.

Teknova 1.5M Tris-HCl, pH 10.0, 1000mL, Sterile. 2 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.
Teknova HBS-EP Buffer (10mM Hepes, 150mM NaCl, 3mM EDTA, 0.005% Tween-20) 200mL, Sterile. 10 pack.
HEPES solution is a Goods buffer that is commonly used in cell culture and biochemical applications. It is well known for its ability to maintain pH level, making it an essential part of any experiment that requires a stable pH. It has a buffering range of 6.8 - 8.2.
Teknova 1M HEPES, pH 6.8. 1000mL, Sterile 2 pack.
HEPES solution is a Goods buffer that is commonly used in cell culture and biochemical applications. It is well known for its ability to maintain pH level, making it an essential part of any experiment that requires a stable pH. It has a buffering range of 6.8 - 8.2.
Teknova DNA Suspension Buffer, pH 8.0. DNase/RNase Tested, PCR Grade. 1mL Tubes, 50-Pack, Sterile.
TE buffer is a salt solution that is commonly used to resuspend (or dilute) DNA and RNA. Composed of Tris base and EDTA, these molecules work together to maintain pH and prevent nucleic acids from degradation.
