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

Alkali Scientific TBE Buffer Powder [TRIS Borate EDTA], 10X Powder, 1702.9 Grams of Powder Makes 10 Liters of Solution
TBE Buffer Powder (Tris-Borate-EDTA), 10X Concentrate, is used extensively in molecular biology applications for DNA and RNA gel electrophoresis. This 1702.9-gram powder makes 10 liters of buffer, providing significant cost savings for laboratories with high-volume needs. The Tris component stabilizes the pH, while Borate facilitates optimal migration of nucleic acids through agarose gels. EDTA acts as a chelator to prevent DNA degradation by binding to metal ions that could activate nucleases. TBE is ideal for large-scale electrophoresis, helping to achieve high-resolution separation of DNA fragments, making it a preferred choice in genomic research, diagnostics, and biotechnology industries.
