Thermo Fisher Scientific Slide-A-Lyzer Dialysis Cassettes 3500K MWCO

Description

Slide-A-Lyzer Dialysis Cassettes use a regenerated-cellulose semipermeable membrane to remove salts and other low-molecular-weight contaminants from proteins and larger macromolecules. The cassette format supports buffer exchange, desalting, equilibrium dialysis and sample concentration while providing a contained chamber for syringe-based sample loading and recovery.

Key Features

• Low-binding regenerated-cellulose membrane for dialysis processing.
• Hermetically sealed chamber helps retain the sample during dialysis.
• Self-sealing gasket supports sample loading and removal with a syringe-mounted hypodermic needle.
• Flat chamber with two membrane surfaces provides a high surface-area-to-volume ratio for diffusion.
• Rectangular frame provides four corner injection ports for sample addition and recovery.

Applications

• Removing salts and other low-molecular-weight contaminants from protein and macromolecule samples.
• Buffer exchange and desalting before downstream purification or analysis.
• Equilibrium dialysis workflows.
• Concentrating liquid protein and macromolecule samples by dialysis.

Specifications

• Molecular weight cutoff: 3.5 kDa.
• Membrane: low-binding regenerated cellulose.
• Membrane hydration before use: 2 minutes.
