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

Boston Bioproducts Inc Phosphate Buffered Saline, PBS (Sterile-Filtered, RNase Free) - 1L
Phosphate Buffered Saline (PBS) is a buffer solution widely used in biological research due to its isotonic and non-toxic nature. With a pH range of 7.0 to 7.4, PBS mimics the osmolarity and ion concentrations of the human body, making it ideal for applications including protein purification, western blotting and immunoassays, sample dilution, and as a transport medium. This buffer is also tested for RNase enzymes, minimizing risk of nucleic acid degredation in downstream applications.

The buffer is biotechnology grade and is formulated for capillary electrophoresis. Buffer is made with 3D water and filtered through 0.22 µ filter. Product is shipped at room temperature.
Bioworld Tris-Glycine Transfer Buffer (10X), 1 L
Tris-Glycine Transfer Buffer, 10X Concentrate.For Western blotting and gel electrophoresis. Tris-glycine buffer is used to make a Tris-glycine-methanol transfer buffer, which is the most common protein transfer buffer for wet blot transfers. The methanol prevents the gel from swelling during the transfer and enhances the protein binding to nitrocellulose.The 10× Tris-glycine buffer is diluted to 1× with methanol and water to make a solution containing 25 mM Tris, 192 mM glycine, and 20% methanol. A sufficient amount of transfer buffer should be made to cover the electrode wires in the wet blot transfer unit and to soak the gel, membrane and blotting paper.To make 1X Transfer Buffer from 10X concentrate: Mix 100 ml of 10X Transfer Buffer, 200 ml of methanol and 700 ml of dd water per liter.Foreign activity: Protease, none detected Storage temp.: 2-8°C
