Protein Purification Reagents – Dextrin Resin (UBPBio catalog# P3080-10, P3080-50) – Dextrin XPure Agarose Resin is a chromatography medium for the isolation of proteins fused to maltose binding protein (MBP-tagged protein). Tagging proteins with MBP often gives increased expression levels and higher solubility of the target protein. Proper folding of the attached protein can be promoted by the MBP tag. Since MBP increases solubility, the tag is particularly useful for recombinant proteins accumulated in an insoluble form (inclusion bodies). Affinity purification using Dextrin XPure Agarose Resin takes place under physiological conditions and mild elution is performed using maltose which preserves target protein activity.
