Sephadex G25 is widely used in biochemistry and molecular biology for the separation and purification of biomolecules. It is particularly effective in desalting and buffer exchange processes, where it helps remove small molecules like salts, dyes, or detergents from protein or nucleic acid solutions. Due to its size exclusion properties, it is also employed in the purification of peptides, oligonucleotides, and other small biomolecules. Additionally, Sephadex G25 is utilized in gel filtration chromatography to fractionate samples based on molecular size, making it a valuable tool in protein research and downstream processing. Its stability and compatibility with aqueous solutions further enhance its application in laboratory workflows.
