Description_x000D_ General description_x000D_ The Pur-A-Lyzer Dialysis Kits are an innovative dialysis tubing that can be conveniently loaded and unloaded using any standard pipette tip while still allowing for 98% sample recovery yield. The revolutionary design of the Pur-A-Lyzer Tube makes it the only dialysis tool which enables true high throughput dialysis, accommodating a large number of samples in a single buffer tank._x000D_ The Pur-A-Lyzer Dialysis Tube allows rapid, high performance extraction of macromolecules without contamination. It is ideal for purification of proteins, automated protein sequencing, peptide mapping and amino acid analysis._x000D_ Application_x000D_ Dialysis or buffer exchange of volumes between 10 mL and 20 mL_x000D_ Preparation of protein samples for MALDI-MS._x000D_ Sample concentration._x000D_ Large-scale protein dialysis such as antibodies and recombinant protein purification._x000D_ Peptide dialysis for molecules as small as 10 amino acids._x000D_ Virus-particle purification._x000D_ Removal of contaminating micro molecules._x000D_ Purification of tissue culture extracts._x000D_ Removal of salts, surfactants, solvents and detergents._x000D_ Complex formation studies (protein-protein, protein-DNA and protein-RNA)_x000D_ pH and buffer adjustment of sample solution, protein extract or cell extract._x000D_ High through- put dialysis, a single beaker can be used for several Pur-A-Lyzer tubes on one floating pad._x000D_ For your convenience the Pur-A-Lyzer kits come in four sizes:_x000D_ Mini: 10 - 250 μL_x000D_ Midi: 50 - 800 μL_x000D_ Maxi:0.1 - 3 mL_x000D_ Mega: 3 - 20 mL_x000D_ Legal Information_x000D_ Pur-A-Lyzer is a trademark of Sigma-Aldrich Co.
