Dialysis Membrane

Dialysis membranes play a crucial role in the field of molecular biology and biochemistry. These semi-permeable membranes are used for separating and purifying molecules, typically proteins or nucleic acids, based on their size and charge. In a dialysis process, a sample is placed within the dialysis membrane, which is then submerged in a solution. Smaller molecules can pass through the membrane, while larger molecules are retained within it. This allows for the exchange of buffer or solvent while effectively separating and concentrating the molecule of interest. Dialysis membranes are vital tools for various laboratory applications, including desalting, buffer exchange, and molecular purification.
