Acrylamide/bis Acrylamide, 37.5:1 Ratio Solution, 1 L, is a liquid solution designed for polyacrylamide gel electrophoresis (PAGE) to separate larger proteins and other macromolecules. The 37.5:1 ratio ensures a less porous gel, ideal for resolving larger molecules while maintaining the structural integrity of the gel. This pre-mixed solution eliminates the need for time-consuming preparation and ensures consistent results. It is extensively used in protein analysis, molecular biology, and proteomics where separation of larger biomolecules is crucial for applications such as western blotting, protein identification, and structural studies.
