Custom Premix Selecting "Custom Premix" option means that all of the beads you have chosen will be premixed in manufacturing before the kit is sent to you.
Each protein preparation is unique. Give it the special treatment it deserves with a perfectly designed device for dialyzing and buffer exchange. Select between fast and gentle dialysis using the D-Tube™ Dialyzers or diafiltration using the Amicon® Ultra Centrifugal Filters.
Gently dialyze intractable or sensitive samples and prevent them from precipitation or over-concentration. Providing maximum efficiency, D-Tubes™ are designed with a double membrane to spread the sample over a large surface area enabling complete dialysis in just two to five hours.
Amicon® Ultra centrifugal devices are ideal for removal or exchange of salts, sugars, nucleotides, and non-aqueous solvents, as well as other materials of low molecular weight. They can also separate free from bound species.
