Reliable Dextran-Based Size Exclusion for High-Yield Purification
Gravity Flow MWCO 25 kDa: For Proteins Larger Than 25 kDa or Nucleic Acids Over 20 bp
CentriPure Gel Filtration Columns with Zetadex-50 are optimized for gravity-based purification and desalting of proteins larger than 25 kDa and nucleic acids longer than 20 bp. They rapidly remove small molecules like salts, dyes, and reaction components while preserving biomolecule integrity—ideal for buffer exchange, oligonucleotide cleanup, and antibody preparation.
Other size-based separation options, differentiated by sample volume and molecular weight cutoff, include:
Gravity Flow MWCO 5 kDa – For proteins >5 kDa or nucleic acids >10 bp
Desalting Column Array – For screening and optimization of multiple sample volumes
