sample preparation

Vivaspin™ Ultrafiltration

Vivaspin™ ultrafiltration columns are designed for rapid, non-denaturing concentration and desalting of target biomolecules in a single tube by combining the size exclusion principle with centrifugation.

Advantages :

• Ease of use
• Sample protection
• High flow rates and minimal membrane blockage due to vertical polyethersulfone (PES) membrane design
• Minimal protein adsorption due to polycarbonate tube design
• Wide choice: suitable for a wide range of sample volumes and molecular weight cut-offs

Extraction, cleaning and amplification

Enrichment with magnetic beads

Magnetic beads to facilitate your manipulations:
enrichment of target proteins using native protein A as ligand; target proteins by immunoprecipitation or pull-down applications; phosphopeptides; target proteins using the strong interaction between the ligands biotin and streptavidin.
Small-scale purification and screening of antibodies using native protein A as ligand or histidine-tagged proteins secreted into eukaryotic cell cultures.
pull-down allowing the rapid capture and enrichment of selected proteins according to their affinity.
