Protein Purification Products

Once expressed proteins are extracted from cell lysates or membranes, affinity chromatography is an elegant way to purify these to homogeneity in very few steps. There are multiple ways to gain this homogeneity, but mostly affinity tags are used in together with a matching purification resin. Cube Biotech offers a broad range of purification agarose resins or magnetic beads for the purification of functional protein. See below what types of resin and magnetic beads we offer.

Not sure which tag to use? See our overview table HERE.

Additionally we offer activated resins and MagBeads for coupling to amino, thiol and carboxy groups directly.

Affinity	Specification	Protein binding
His-tag-Affinity Agarose & MagBeads	Due to its very small size it rarely affects protein function. High protein yields!	His-tagged proteins
Glutathione / GST tag Agarose & MagBeads	The GST tag is a 26 kDa protein tag which is often chosen to promote recombinant protein folding.	GST-tagged proteins (Glutathione-S-Tranferase)
Strep-tag Affinity Agarose & MagBeads	The Strep-tag® is a 8 amino acid tag with high specificity for StrepTactin®. Highly specific.	Strep-tagged proteins
Rho1D4 / 1D4 tag Affinity Agarose & MagBeads	The-Rho1D4-tag is a 9 amino acid tag that binds to the rho1D4 antibody. Our most specific affinity tag!	rho1d4 tagged proteins
Hydrophobic Interaction Agarose	Agarose resin / MagBeads that carry a hydrophobic group for matching interactions with a protein.	Hydrophobic amino acid residues.
Alprenolol Resins	A resin for a highly spezialized purpose.	ß-adrenergic receptors and alkene functions
