Thermo Scientific™ Plaques de dessalage Zeba™ Spin, seuil de rétention des molécules de 7 000

Description

Dessalez rapidement des échantillons biologiques et de protéines pour la chromatographie liquide (LC) manuelle ou automatisée avec les colonnes, plaques et cartouches de dessalage par centrifugation Thermo Scientific Zeba, qui permettent une rétention de ≥ 95 % des sels et des autres petits contaminants moléculaires (< 1 000 Da). Les produits de dessalage par centrifugation Zeba contiennent une résine exclusive haute performance pour chromatographie d’exclusion stérique qui permet un dessalage supérieur et une excellente récupération des protéines avec un seuil de rétention des molécules (MWCO) de 7 000 dans un format pour centrifugeuse.

Zeba Spin Desalting columns, plates, and chromatography cartridge fittings are convenient, ready-to-use devices compatible with major automated liquid-chromatography systems or for manual syringe processing. The polypropylene columns have a 7K MWCO and contain a proprietary high-performance size-exclusion chromatography resin (Zeba High-Performance Resin) that offers excellent protein desalting and recovery in a centrifuge format. When using Zeba Spin Desalting Columns, even very dilute (25 μg/mL) protein samples can be successfully processed to obtain greater than 95% retention (removal) of salts and other small molecules (<1000 MW), and good recovery of proteins and other macromolecules (>7000 MW).

Similarly, Zeba Desalting plates (7K MWCO) are polypropylene devices that contain Zeba High-Performance Resin and provide excellent protein desalting performance, with high recovery of proteins >7000 Da in a centrifuge format for small sample volumes. The plates enable fast, consistent, well-to-well and plate-to-plate reproducibility for small-scale, high-throughput separations. Zeba 96-well spin desalting plates require no resin dispensing or hydration and provide the same high protein recovery as spin columns with at least 95% removal of salts and other small molecules. One plate can process 96 small sample volumes (20 to 100 μL) in just five minutes, offering rapid and exceptional protein desalting.

The Zeba Desalting Chromatography Cartridges contain Zeba High-Performance Resin for desalting or buffer exchange applications. This resin is ideal for removing low molecular weight compounds including salts, fluorescent dyes, biotin, and other small labeling reagents. Protein samples can be processed with unsurpassed protein recovery and 95% retention of salts and other small molecular contaminants (<1,000 Da). Zeba Desalting cartridges provide fast, easy, and reproducible chromatographic separations and can be regenerated for multiple uses.

Benefits of Zeba Spin Desalting columns, plates, and cartridges include:

• High recovery—low-binding resin maximizes protein recovery
• Fast—no fraction screening or waiting for protein to emerge by gravity flow
• Economical—great performance at lower cost than other commercially available cartridges
• Easy-to-use—no cumbersome column preparation or equilibration
• Flexible—available in spin columns, filter spin plates and cartridges for a range of needs

Available formats

• Spin columns—75 μL, 0.5 mL (microcentrifuge), 2 mL, 5 mL, 10 mL columns
• 96-well spin plates—pre-dispensed 96-well filter plates, compatible with centrifugation for manual or automated purification
• Chromatography cartridges—compatible with automated liquid chromatography systems and with syringe processing
