Size Exclusion Chromatography

Generally, in biochemical protein purification applications, size exclusion chromatography (SEC) is the last step used. This technique purifies DNA and proteins based on their sizes, and it holds many advantages such as the ability to separate larger molecules from smaller molecules, remove salt contamination and it can be used for the determination of quaternary protein structure. GoldBio offers a large selection of agarose beads for size exclusion chromatography, which are excellent for your unique research needs.

2% Agarose Beads, Standard

Catalog ID Size Pricing
A-181-500 500 mL $ 518.00
A-181-1000 1 L $ 821.00

Description

Agarose is a very inert polysaccharide that forms hydrophilic and high gel strength gels at low concentrations.
Agarose beads are microspheres of agarose gels with different particle diameters and concentrations. Small spherical particles of agarose act as a porous gel to filter or separate a mixture of molecules according to their individual sizes. Due to its chemical structure (easy to activate), the agarose beads may be prepared to bind biomolecules in a reversible or irreversible manner. Plain agarose beads are used in gel filtration chromatography (or molecular exclusion chromatography) as well as for activating beads for biomolecule purification or immobilization.
Plain agarose beads can also be used for activating processes, generating active groups inside its pores capable of reversible or irreversible biomolecule bonds. Due to the bead’s large internal surface and to its composition (inert polysaccharide), agarose is an ideal medium for the preparation of activated beads.

Catalog ID Size Pricing
R-200-500 500 mL $ 762.00
R-200-1000 1 L $ 1,076.00

Description

This matrix is a highly cross-linked 4% agarose bead with a bead size of 50-150 µm. It is a gel filtration resin developed for industrial-scale separation of large molecules and virus particles utilizing higher pressure and flow rates rather than low pressure standard beads.

This matrix is not preactivated. For preactivated resins, look for Aminoethyl Agarose Beads, Glyoxal Agarose Beads, Protein A or Protein G.
