Description
Dry gel filtration spin column for fast protein and oligonucleotide cleanup
CentriPure DRY Z-50SF from emp BIOTECH is a non-hydrated, sterile-packed spin column filled with Zetadex-50 Superfine resin. Ideal for labs requiring flexible buffer systems, this dry format allows researchers to hydrate the resin with their buffer of choice. It efficiently removes salts, dyes, dye terminators, and unreacted labels from proteins >25 kDa and oligonucleotides >20 bp.
Performance Highlights
- For proteins >25 kDa and oligos >20 bp
- Non-hydrated format – hydrate with buffer of choice
- Superfine resin for high-resolution cleanup (20–50 µm)
- Desalting, dye and label removal in a single step
- Compatible with centrifugation workflows
