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 bis TRIS [bis (2 hydroxyethyl)aminotris(hydroxymethyl)methane], 1 Kg
Bis TRIS (bis(2-hydroxyethyl)aminotris(hydroxymethyl)methane) is available in a high-purity 1 kg powder form, ideal for high-volume laboratories and research applications requiring precise pH control in the alkaline range. This buffer is commonly used in protein electrophoresis, enzyme kinetics studies, and biochemical analysis. Bis TRIS offers excellent buffering capacity at pH values above 7.0, making it particularly useful in applications where pH stability is essential. The 1 kg package is a cost-effective option for laboratories conducting large-scale experiments, offering reliable performance for extended periods. Bis TRIS is frequently used in academic, clinical, and pharmaceutical research settings where exact pH control is critical for experimental accuracy.

AdipoGen Trishydroxymethyl aminometha
Chemical. CAS 77-86-1. Formula C4H11NO3. MW 121.14. Synthetic. A high quality buffer used in the range of physiological pH 7-9. Widely used as a biological buffer or as a component of buffer formulations. Tris has a pKa of 8.06 and is very useful in the biology and biochemistry lab because it has buffering capabilities in the range of the typical physiological pH of most living organisms pH 7.0-9.0. Tris has been reported to interfere with the activity of a number of enzymes, it should therefore be used carefully when studying proteins.
