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 TRIS, Amino Buffer, Enzyme Grade, 5 Kilograms
TRIS Amino (Enzyme Grade) buffer is a high-purity solution designed specifically for enzyme-related applications in molecular biology and biochemistry. This 5kg package provides an ample supply of this reagent, which is widely used for preparing enzyme buffers in assays such as enzyme-linked immunosorbent assays (ELISA), protein assays, and PCR. The TRIS Amino buffer maintains stable pH conditions critical for optimal enzyme activity, and its enzyme-grade quality ensures minimal impurities that could interfere with biochemical reactions. This buffer is ideal for use in experiments where precise pH control is required for enzymatic reactions, as well as for preparing buffers for enzyme activity studies and protein purification.

Bioworld TAE Buffer (50X), 4 L
Product DescriptionTAE (Tris-Acetate-EDTA) buffer liquid concentrate has a 50X concentration and is filtered through a 0.22 µm membrane. It has a pH of 8.5 ± 0.1. A concentration of 1X contains 0.04M Tris, 0.02M acetate, and 0.001M EDTA. 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.
