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 Glycine SDS Buffer, 10X Powder, 184 Grams of Powder, Makes 1 Liter of Solution
TRIS Glycine SDS Buffer (10X Powder) is a commonly used buffer solution in electrophoresis and protein separation techniques. This 184g powder is designed to make 1 liter of 10X concentrated solution, ideal for preparing protein gels for SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis). The buffer helps maintain a consistent pH and conductivity during protein separation, ensuring reproducible results. It is widely used in laboratories for protein analysis, molecular biology applications, and biochemistry experiments. TRIS Glycine SDS Buffer is essential for the proper functioning of electrophoresis systems, helping researchers isolate proteins based on size and charge in a reliable and efficient manner.

Medchemexpress LLC P62-mediated mitopha 100mg | 1809031-84-2 | 392.15 | C14H9IN4O2 | 100 MG
P62-mediated mitophagy inducer (PMI) is a small-molecule activator of p62-mediated mitophagy used as a pharmacological tool to study mitophagy pathways. It activates mitochondrial autophagy without recruiting Parkin or collapsing mitochondrial membrane potential, and it stabilizes Nrf2 and upregulates p62 at active concentrations.
- Activates mitochondrial autophagy independent of Parkin recruitment.
- Remains active in cells lacking a fully functional PINK1/Parkin pathway.
- Stabilizes Nrf2 and upregulates p62 expression at effective concentrations.
- Well characterized by NMR, HRMS, and elemental analysis for research applications.
- Solid compound, soluble in DMSO for stock preparation.

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.
