Sephadex

Sephadex is a type of gel used in laboratories to separate molecules based on their size. It’s made of tiny, porous beads that allow smaller molecules to enter and move through easily, while larger molecules are excluded and pass around the beads more quickly. This process, called gel filtration or size-exclusion chromatography, helps scientists analyze, purify, or identify different molecules such as proteins, DNA, or sugars. Sephadex is commonly used because it is stable, easy to handle, and allows precise separation for research and medical purposes.
