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 Acetate Ultra Pure, 1 Kg
Tris Acetate Ultra Pure is a high-purity buffering agent used in a variety of biochemical applications. This reagent is ideal for high-precision applications such as electrophoresis, protein analysis, and other laboratory techniques requiring a stable pH. The ultra-pure grade ensures minimal interference with sensitive experiments, maintaining the integrity of reactions. This 1kg bottle is perfect for large-scale buffer preparations, providing consistent buffering power across a range of experiments. Tris acetate is commonly used in molecular biology, immunology, and protein chemistry, particularly for its ability to maintain a stable pH in high-purity systems.
Selleck Chemical LLC P62-mediated mitophagy inducer
P62-mediated mitophagy inducer (PMI) is a P62-mediated activator of mitophagy that functions independently of parkin recruitment or mitochondrial membrane potential ( m) collapse It remains effective even in cells lacking a fully functional PINK1/Parkin pathway PMI stabilizes Nrf2 and enhances p62 expression thereby activating mitophagy
