What is a Superdex column?
Superdex Increase 200 is a column for high resolution gel filtration in small scale (mg) preparative purification and also for characterization and analysis of proteins with molecular weights between 10,000 and 600,000, such as aggregate analysis of antibodies, size-homegeneity analysis of membrane proteins, or protein …
What the difference between superdex 75 and 200?
Comparison between Superdex 200 Increase and Superdex 75 Increase. Superdex 75 Increase gives higher resolution of proteins with Mr ≤ 44 000. Superdex 200 Increase shows better resolution for proteins above this molecular weight.
How do you clean the size of the exclusion column?
If the column is to be stored for more than 2 d after use, wash it with 2 CV of water and then equilibrate with at least 2 CV of 20% ethanol (for HiLoad Superdex 30 pg and Superdex 75 pg, use 200 mM sodium acetate in 20% ethanol). Note: Use a lower flow rate for viscous 20% ethanol.
What superdex 75?
Superdex 75 Increase prepacked columns are designed for rapid separation and analysis of proteins with molecular weights ranging from Mr 3000 to 70 000 by size exclusion chromatography (SEC), also called gel filtration (Fig 1).
What is FPLC system?
Fast protein liquid chromatography (FPLC) is a form of medium-pressure chromatography that uses a pump to control the speed at which the mobile phase passes through the stationary phase.
What is Sepharose used for?
Sepharose/agarose, combined with some form of activation chemistry, is also used to immobilize enzymes, antibodies and other proteins and peptides through covalent attachment to the resin.
How do you clean a Superdex column?
Why are columns stored in 20% ethanol?
SEC columns from Cytiva are equilibrated with storage solution, which is degassed 20% ethanol. Because ethanol is a viscous solution, a slow flow rate must be used to avoid compressing the packed bed. I recommend using approximately 50% of the maximum flow rate for your column.
What is FPLC column?
FPLC (Fast Protein Liquid Chromatography) is, as its name suggests, a liquid chromatography that is often used to analyze or separate compounds from a mixture of proteins. In FPLC, the mobile phase is an aqueous solution or buffer. The stationary phase is a resin contained in a column.

What is Sepharose column?
Protein A Sepharose® Columns display high chemical and physical stability as well as high flow rate, hydrophilicity and high gel strength. This product can be used for IgG purification and immunoprecipitation.
What is the difference between agarose and Sepharose?
Pure agarose is powdered form while sepharose is more beaded in structure. Agarose is a more generic term referring to a type of polysaccharide polymer while sepharose is a trademarked term by GE Healthcare. 3. Agarose has more charged polysaccharides compared to sepharose.
What is Superdex 75 10/300 GL?
Superdex® 75 10/300 GL is a prepacked gel filtration column for high-resolution, semipreparative, and analytical separations of biomolecules. Superdex® 75 has a separation range for molecules with molecular weights between 3 000 and 70 000.
What is Superdex 75 increase column used for?
The columns are intended for use in preparative purification as well as for characterization and analysis of proteins with molecular weights between M r 3000 and 70 000, such as recombinant tagged proteins. Superdex 75 Increase 10/300 GL, 5/150 GL, and 3.2/300 are prepacked columns for versatile use in size exclusion chromatography applications.
Is supersuperdex 75 increase resin alkali-resistant?
Superdex 75 Increase resin is alkali-resistant. Hence, the column can be cleaned in place under alkali conditions to allow use of the same column for different proteins with minimal risk for carryover between samples. The alkali resistance is what differentiates agarose-based resins from silica-based resins.
What is the maximum concentration of protein in Superdex?
