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

Bioworld TT - SDS Running Buffer (Cathode) (10X), 500 mL
Product DescriptionTris-Tricine (TT)-SDS running buffer has a 10X concentration and a pH of 8.3. It contains 1M Tris-base, 1M Tricine and 1% SDS.The tricine system requires SDS in sample and running buffers for best results. Tricine-SDS PAGE is commonly used to separate proteins that range in molecular weight between 1 – 100 kDa but is preferred for the resolution of proteins smaller than 30 kDa.
Research Products International Corp TRIS BUFFERED SALINE, 10X SOLUTION, 10 LITER
TBS 10X Solution (Tris Buffered Saline) is a concentrated buffered salt solution containing Tris and sodium chloride. It maintains pH stability and provides ionic strength for biological experiments. Tris acts as a buffering agent to keep pH consistent, while sodium chloride mimics physiological conditions. Dilute 10X solution with distilled water to prepare working concentrations (e.g., 1X). TBS is widely used in protein and nucleic acid blotting, immunohistochemistry, and molecular biology techniques, ensuring stable and reproducible results across diverse applications.
Teknova 1M Tris-HCl, pH 8.3. 500mL, Sterile. 4 pack.
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.
Teknova DNA Suspension Buffer, pH 8.0. DNase/RNase Tested, PCR Grade. 1mL Tubes, 50-Pack, Sterile.
TE buffer is a salt solution that is commonly used to resuspend (or dilute) DNA and RNA. Composed of Tris base and EDTA, these molecules work together to maintain pH and prevent nucleic acids from degradation.

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
