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
Teknova 1M Tris-HCl, pH 8.0 Solution. 1000mL, Sterile.
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.
Boston Bioproducts Inc Tris-HCl Buffer (1 M, pH 8.0) - 500ml
The Tris-HCl Buffer is a widely used bufering reagent in molecular biology and biochemistry, acting to maintain a stable pH, and preserve the integrity of target macromolecules. The buffering capacity of Tris-HCl is effective in the pH range of 7.0 to 9.0, making it ideal for many biological applications like cell culture, molecular biology, DNA/RNA extraction, electrophoresis, enzyme assays and immunohistostaining.
Boston Bioproducts Inc PIPES Buffer (0.5 M, pH 6.8) - 100ml
The PIPES Buffer is a zwitterionic buffering agent commonly used in biochemistry and molecular biology for its ability to maintain a stable pH. With a pKa of approximately 6.8, PIPES is effective in the pH range of 6.1 to 7.5, making it suitable for cell culture, enzyme assays, protein purification, and as a running buffer in gel electrophoresis. PIPES is also used in electron microscopy, protein crystallization, and isoelectric focusing and chromatography.
Boston Bioproducts Inc Tris-Acetate-EDTA Buffer, TAE (50X) - 4L
The Tris-Acetate-EDTA (TAE) Buffer is a pH regulator and chelator often used in molecular biology techniques such as agarose gel electrophoresis. Supporting a pH range of 8.1-8.4, the TAE Buffer combines tris base, acetic acid, and EDTA (Ethylenediaminetetraacetic Acid) to form a solution efficient in separating nucleic acids as a running buffer, or as a component of agarose gels. This Buffer is prepared in a 50X stock solution, and can be diluted to ideal concentrations.
